#### What Might A Microwave Oven Imply About Measuring Microwaves Emitted By The Sun On Earth? (Solution found)

When using a microwave oven, what is the maximum quantity of radiation it may emit?

• At roughly 2 inches from the oven surface, a Federal requirement (21 CFR 1030.10) restricts the quantity of microwave radiation that can leak from an oven throughout its lifetime to 5 milliwatts (mW) of microwave radiation per square centimeter for its entire lifetime. This limit is far lower than the threshold at which humans are known to be harmed.

## Why would Astronomers be interested in placing a gamma ray detecting observatory in space?

Some things exclusively produce radio waves, whereas others only release X-rays. This is why it is critical to conduct research into the Universe using various types of space observatories. Astronomers are able to see these catastrophic events and determine the precise way in which they affect the Universe because they capture gamma rays.

## How do astronomers save their eyes when looking at the sun through a telescope quizlet?

When staring at the Sun through a solar telescope, your eyes would be instantly incinerated. So, how can astronomers keep their eyes safe when looking at the Sun? They may transmit the image captured by the telescope onto a huge screen or record it with a camera.

## What is the main factor that determines what will happen to a star after it consumes all of its nuclear fuel?

The overall mass of a star is the most important component in determining the course of its evolution and ultimate fate. An active star’s light is produced by the thermonuclear fusion of hydrogen into helium in its core, which releases energy that travels through the star’s interior and eventually radiates into outer space for the majority of its lifespan.

## What principle do astronomers use to determine whether a celestial body is approaching or receding from Earth?

His next step was to apply what he had learnt to all waves, including light. He observed that, depending on whether the light source was approaching or retreating from the observer, the light waves would be packed closer together or split further apart, respectively. Figure 1 depicts a broad illustration of the idea, which is today known as the Doppler effect.

## Why is it important that Earth’s atmosphere absorbs gamma rays emitted by the sun?

Gamma rays are extremely energetic and have the potential to cause harm to people on Earth. The Earth’s atmosphere shields people from the harmful effects of gamma radiation. The atmosphere absorbs gamma rays, preventing them from having an adverse effect on life on Earth, as previously stated. Because gamma rays cannot penetrate the Earth’s atmosphere, scientists must conduct their research from space using satellites.

## How do astronomers use electromagnetic radiation to study space?

When studying objects in space, astronomers employ a variety of telescopes that are sensitive to different sections of the electromagnetic spectrum. Despite the fact that all light is basically the same thing, the method in which astronomers see light varies depending on the region of the spectrum they are interested in exploring.

## What do streams of protons and electrons emitted from the Sun produce?

The Solar Wind, to be precise. It has been discovered that the Sun’s atmosphere emits a stream of charged particles (mostly protons and electrons), which we refer to as the solar wind. This is one of the most astonishing discoveries concerning our star.

## What is the ideal way if cost is no object?

Without regard to cost, what is the best approach for a telescope to prevent being affected by air disturbance? It should be placed in the appropriate location. There are Numerous telescopes named after Galileo. Astronomers are in order to increase the resolution of radio telescopes.

## What does the Sun emit that is invisible?

Light That Isn’t Visible Ultraviolet (UV) light is a kind of high-energy radiation that is invisible to the human eye and belongs to the electromagnetic spectrum. UVA radiation, which accounts for 95 percent of all UV radiation released by the sun, penetrates the skin more deeply than UVB radiation and is a contributing factor to the aging and wrinkling of skin, as well as skin cancer (also called photoaging).

## What determines if a star becomes a giant or a supergiant?

Stars undergo variations in their internal composition as a result of the hydrogen-helium fusion that occurs within them, which results in changes in their temperature, brightness, and radius. Once a star reaches a certain age, it begins to grow away from the main sequence and becomes a red giant or a supergiant.

## What is the largest factor that determines the path a star will take through its life cycle?

The mass of a star determines the length of its life cycle. The greater the bulk of an object, the shorter its life cycle. In the nebula from which a star was created, the quantity of matter accessible in the cloud of gas and dust that formed the star is what determines the mass of the star.

## What type of star emits the most energy?

Stars operate in a manner similar to that of blackbodies, and this notion helps to explain why there are diverse hues in the sky. Red stars are cooler than white stars, and they release the greatest energy at wavelengths in the red range. A hotter star, such as our sun, releases the greatest amount of radiation in the yellow/green portion of the electromagnetic spectrum.

## Why do astronomers measure the motion of the star instead of measuring the motion of the planet directly?

The reason for this is that, because the stars are so far away, it takes years for even the smallest alteration to become noticeable.

## How can astronomers determine whether a star is moving toward or away from Earth?

A star’s Doppler shift may be determined by looking at the colors of the light it emits, which allows astronomers to determine how rapidly the star is moving in relation to the earth. The color of light can shift from one spectral wavelength to another spectral wavelength if the velocity of the source is correct.

## Which of the following can astronomers determine from the spectrum of an object choose one or more?

Astronomers can identify not only the element, but also the temperature and density of that element in the star, based on the spectral lines observed. In addition, the spectral line can provide information about the star’s magnetic field. The breadth of the line can provide information about the speed at which the material is traveling. This provides us with information on the winds in the stars.
