A light wave passes from air into water. Which of its properties (speed, wavelength, frequency) remains the same?
The frequency of the light wave remains the same when it passes from air into water.
What are the two possible behaviors of a wave when it encounters a boundary between two different media?
A wave that travels from one medium to another can be transmitted through the new medium or reflected back from the boundary.
Define polarization of a wave.
Polarization is the process by which a transverse wave's oscillations are restricted to a single plane.
How does the oscillation of a polarized transverse wave differ from an unpolarized one?
A polarized transverse wave oscillates in a single plane, whereas an unpolarized one oscillates in multiple planes perpendicular to its direction of travel.
Which general type of wave can be polarized?
Transverse waves are the type of waves that can be polarized.
What is a reflected wave?
A reflected wave is the portion of a wave that bounces off the boundary separating two media.
What determines whether a wave is transmitted or reflected at a boundary?
The properties of the boundary separating the two media determine the extent to which a wave is transmitted or reflected.
Can a sound wave traveling through water be polarized? Explain.
No, a sound wave cannot be polarized because it is a longitudinal wave.
Why can't longitudinal waves be polarized?
Longitudinal waves cannot be polarized because their oscillations are already confined to the direction of wave travel.
What property of a wave remains constant when it passes from one medium to another?
The frequency of a wave does not change when it travels from one medium to another.
What is a transmitted wave?
A transmitted wave is the portion of a wave that passes through the boundary separating two media.
