9 Em Waves and Light- test REVIEW (ac)

Front

What happens to white light when it enters a prism?

Back

White light is refracted into its component colors, with the color having the longest wavelength (red) being refracted the least.

Front

Who demonstrated that white light consists of many colors?

Back

Sir Isaac Newton.

Front

What does the number 3 represent in wave terminology?

Back

Amplitude.

Front

What is the part of the wave called that is associated with compression?

Back

Compression.

Front

Do sound waves travel slower in hotter air?

Back

False; sound waves travel faster in hotter air.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another.

Front

What is the visible spectrum?

Back

The visible spectrum is the range of colors that can be seen by the human eye, typically represented as red, orange, yellow, green, blue, indigo, and violet.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves oscillate perpendicular to the direction of wave travel, while longitudinal waves oscillate parallel to the direction of wave travel.

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second (km/s).
