Nature of Light & Sound

What is the typical speed of light in a vacuum?

Which of the following is not part of the electromagnetic spectrum?

• Gamma rays

• Sound waves

• Ultraviolet light

• Infrared light

What does the wave-particle duality theory suggest about photons?

• Photons are only particles

• Photons are only waves

• Photons can exhibit properties of both waves and particles

• Photons are neither waves nor particles

What is the relationship between pitch and frequency of a sound wave?

• Higher pitch means lower frequency

• Higher pitch means higher frequency

• Pitch and frequency are unrelated

• Pitch is the amplitude of the wave

What happens to light when it undergoes refraction?

• It bends away from the normal

• It travels in a straight line

• It bends towards the normal

• It disappears

Which phenomenon is best described by the Doppler effect?

• The bending of light around corners

• The change in frequency of a wave relative to an observer who is moving relative to the wave source

• The interference pattern of waves

• The polarization of light

What is the frequency range of visible light?

What occurs during the reflection of light?

• Light is absorbed by the surface

• Light passes through the surface

• Light bounces off the surface

• Light is refracted through the surface

Which color of visible light has the shortest wavelength?

• Red

• Green

• Blue

• Violet

What is the unit of frequency?

• Hertz (Hz)

• Newton (N)

• Joule (J)

• Watt (W)
