EM waves Review

The sun's energy comes in many different forms of electromagnetic radiation, as shown. Which form of solar radiation has a longer wavelength than white light?

• Infrared

• Gamma Rays

• Ultraviolet

• Visible Light

What is the name for a rainbow of colors that results when white light shines through a prism?

• Radio Wave

• Thermal Energy

• Visible spectrum

• electromagnetic radiation

Bluetooth is a technology that allows wireless devices to communicate data and information to each other. For example, a wireless pair of headphones can play music from a smart phone without a physical connection. However, the technology must be low energy enough not to cause damage to the people using the device. Additionally, the wavelengths used in bluetooth technologies should not be visible. The waves associated with Bluetooth technology are most similar to which wave type?

• X-rays

• Red Light

• Radio Waves

• UV radiation

An automobile owner notices that when her car is outfitted with a muffler, the sound from the exhaust pipe is much quieter than without the muffler. When she asks her automobile technician about how a muffler works, he explains that a muffler is a device that matches the sound coming down the exhaust pipe but with waves out of phase from the pipe. What phenomenon is the automobile noticing and the technician describing?

• Seismic Waves

• Doppler Effect

• Destructive interference

• Constructive interference

Spearfishing is a skill that takes a long time to master. This is because the actual position of the fish is different from where the fish appears to be when viewed from above the water.

• The fish reflecting the light

• the water diffracting the light

• the water refracting the light

• the fish focusing the light
