absorption
refraction
reflection
diffraction
Clear selection
Which wave phenomenon makes it possible for a player to hear the sound from a referee’s whistle in an open field even when standing behind the referee?
reflection
Doppler effect
refraction
diffraction
Clear selection
Which statement describes a characteristics common to all electromagnetic waves and mechanical waves?
Both types of waves travel at the same speed.
Both types of waves transfer energy.
Both types of waves require a material medium for propagation.
Both types of waves propagate in a vacuum.
Clear selection
For a given frequency of a longitudinal wave, which characteristic is directly related to the energy of the wave?
speed of wave
amplitude
period
wavelength
Clear selection
Two waves having the same frequency and amplitude are traveling in the same medium. Maximum constructive interference occurs at points where the phase difference between the two superposed waves is
270°
90°
0°
180°
Clear selection
The image is for this question. The wave pattern is produced by two wave sources located at points A and B. Which phenomenon occurs at the intersections of the circular wave fronts?
refraction
diffraction
interference
reflection
Clear selection
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
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
amplitude and frequency of the incident wave
Clear selection
A laser beam does not disperse as it passes through a prism because the laser beam is
monochromatic
longitudinal
polarized
polychromatic
Clear selection
A helium-neon laser emits energy in the visible red region in the form of
photons
gamma rays
electrons
alpha particles
Clear selection
Diffraction of light demonstrates that light
can be reflected
can be polarized
has wave properties
is composed of tiny units of energy
Clear selection
Interference and diffraction can be explained by
the wave theory, only
the particle theory, only
neither the wave nor particle theory
both wave and particle theory
