Waves, Sound, and Physical Optics
What primarily determines whether a wave will be transmitted or reflected at a boundary between two media?
The color of the media.
The properties of the boundary separating the two media.
The temperature of the surrounding environment.
The observer's point of view.
A wave travels from a low-mass string to a high-mass string. What happens to the wave at the boundary?
Only transmission occurs.
Only reflection occurs.
Both reflection and transmission occur.
The wave stops at the boundary.
Under what condition will a reflected wave be inverted at a boundary?
When the transmitted wave speed increases in the new medium.
When the transmitted wave speed decreases in the new medium.
When the frequency of the wave increases.
When the frequency of the wave decreases.
A wave travels from a medium where its speed is to a medium where its speed is . If , what happens to the reflected wave?
It is inverted.
It maintains its orientation.
It disappears entirely.
Its frequency changes.
What remains constant when a wave crosses a boundary between different media?
Wave speed
Wavelength
Wave frequency
Wave amplitude
Which type of wave can undergo polarization?
Longitudinal waves
Transverse waves
Sound waves
All types of waves
What is the effect of polarization on transverse waves?
It increases their speed.
It restricts their oscillations to a single plane.
It increases their amplitude.
It changes their frequency.

Why can't longitudinal waves be polarized?
They have very high speeds.
They do not interact with media.
Their oscillations are parallel to their direction of travel.
Their oscillations are perpendicular to their direction of travel.
What happens to wave intensity due to polarization?
It increases.
It decreases.
It remains constant.
It oscillates.
Wave intensity is quantified as:
Total energy of the wave.
Average power transferred per unit area over one wave period.
Maximum displacement of the wave.
The speed of the wave.
