Wave Diffraction

This image depicts which of the following wave behaviors?

• Reflection

• Refraction

• Diffraction

• Resonance

Definition: The spreading out of waves as they pass through an opening or around objects.

• Reflection

• Refraction

• Diffraction

• Resonance

Light waves and sound waves are similar in that...

• They are both longitudinal waves

• They are both transverse waves

• They both transmit energy

• They both can travel through space.

A wave of constant wavelength diffracts as it passes through an opening in a barrier. As the size of the opening is increased, the diffraction effects

• decrease

• increase

• remain the same

The diagram shows a series of wave fronts approaching an opening in a barrier. Point P is located on the opposite side of the barrier. The wave fronts reach point P as a result of

• resonance

• refraction

• reflection

• diffraction

Which wave phenomenon makes it possible for a player to hear sound from a referee's whistle in an open field even when standing behind the referee?

• diffraction

• Doppler effect

• reflection

• refraction

A wave is diffracted as it passes through an opening in a barrier. The amount of diffraction that the wave undergoes depends on both the

• amplitude and frequency of the incident wave

• wavelength and speed of the incident wave

• wavelength of the incident wave and the size of the opening

• amplitude of the incident wave and the size of the opening

Parallel wave fronts incident on an opening in a barrier are diffracted. For which combination of wavelength and size of opening will diffraction effects be greatest?

• short wavelength and narrow opening

• short wavelength and wide opening

• long wavelength and narrow opening

• long wavelength and wide opening

Radio waves diffract around buildings more than light waves do because, compared to light waves, radio waves

• move faster

• move slower

• have a higher frequency

• have a longer wavelength
