Wave Behavior and Properties

The video tutorial explores wave behavior at boundaries, focusing on reflection and transmission. It explains how waves interact with fixed and free boundaries, causing phase changes. Torsional waves are discussed, highlighting their reflection properties. The tutorial also covers wave transmission between media of different densities, affecting wave speed and wavelength.

What happens to a wave when it encounters a fixed boundary?

• It disappears.

• It passes through without any change.

• It is absorbed completely.

• It is reflected with a phase change.

How does a wave behave when it hits a free boundary?

• It is reflected with a phase change.

• It is absorbed completely.

• It is reflected without a phase change.

• It disappears.

In the demonstration, what phase change occurs at a fixed boundary?

• 2Pi

• None

• Pi

• 0

What happens to the wave at a free boundary in the demonstration?

• It is absorbed.

• It is reflected with a phase change of Pi.

• It is reflected with no phase change.

• It disappears.

What occurs when a wave moves from a low-density to a high-density medium?

• The wave remains unchanged.

• The wave disappears.

• The wave slows down.

• The wave speeds up.

How does the wave behave when moving from a high-density to a low-density medium?

• It slows down.

• It speeds up.

• It disappears.

• It remains unchanged.

What remains constant when a wave transitions between different media?

• Velocity

• Wavelength

• Frequency

• Amplitude

What happens to the wavelength when a wave moves into a more dense medium?

• It decreases.

• It remains the same.

• It increases.

• It disappears.

What is the effect on wave speed when moving to a less dense medium?

• The speed becomes zero.

• The speed remains the same.

• The speed increases.

• The speed decreases.

Why do waves get more compressed in a denser medium?

• Because the amplitude increases.

• Because the frequency increases.

• Because the wavelength increases.

• Because the velocity decreases.
