Look at the diagram of a liquid heated with microwaves. How do microwaves interact with matter and generate heat?

Microwaves cause the particles in objects to move faster, thus increasing the heat of the object. ▲

Microwaves reflect off the surface of matter which causes it to heat up.

Microwaves are high-energy waves that transfer this energy into matter and break down atoms to create heat.

Microwaves are heat waves that transfer through matter.

If the speed of a wave is constant, what happens to the frequency of the wave if the wavelength increases?

The frequency increases then decreases.

The frequency remains constant.

A scientist discovers a substance that emits electromagnetic waves with a higher frequency than UV rays. Which statement about the mystery waves is always true?

They will have a shorter wavelength than UV rays.

They will have a smaller amplitude than UV rays.

They will have a larger amplitude than UV rays.

They will have a larger wavelength than UV rays. ▲

Doctors can use high-energy electromagnetic radiation to kill cancer cells. What type of electromagnetic waves can doctors use?

They can use gamma rays. Because they have high frequency and a short wavelength, they have enough energy to kill cancer cells.

They can use microwaves. Because they have a low frequency and a short wavelength, they have enough energy to kill cancer cells.

They can use infrared waves. Because they have a low frequency and are visible to the human eye, the doctor can aim the radiation energy to kill cancer cells.

They can use white, or visible, light. Because it has the highest energy of all electromagnetic waves, it is the only one that can kill cancer cells. ▲

Colored fabrics left out in the sun often fade from the electromagnetic waves they receive. How would this observation change if the ozone layer were thinner and had less power to affect incoming UV radiation?

More ultraviolet radiation would reach Earth, causing fabrics to fade even more quickly.

There would be more infrared radiation that would reach Earth and cause fabrics to fade even more.

Less ultraviolet radiation would reach Earth and the fabrics, which would fade less and appear brighter over time.

There would be more visible light that would reach Earth and cause fabrics to appear brighter.

Electromagnetic waves can be reflected and refracted. Which of the following examples demonstrate refraction of electromagnetic waves? Select TWO responses.

A camera lens bends light to bring close or distant items into focus when you take a picture.

A straw in a glass of water appears to be broken in half because light waves change direction as they pass through the different materials. ▲

Light from the surroundings bounces off the side mirror, so the bus driver can see what vehicles are on the road behind the bus.

Light travels from surrounding objects and hits the water of a lake, then travels to your eye, causing you to see an image of the surrounding landscape on the surface of the water.

Astronomers use different types of telescopes to observe different parts of the electromagnetic spectrum. This allows astronomers to study objects in space. Some electromagnetic waves are blocked by Earth’s atmosphere, making it difficult for astronomers to focus the energy into a viewable image. Instead of actually viewing the energy, astronomers have learned to view the interactions of the energy with the atmosphere. These faint interactions with the atmosphere allow them to study highly energetic objects such as pulsars and black holes.

If the waves that are being observed have a frequency of 10²², what type of wave is being observed?

Gamma

Radio

Xray
