Standing Waves and Wave Behavior

The video tutorial covers various wave behaviors, including reflection, refraction, interference, and standing waves. It explains how these behaviors affect wave characteristics such as frequency, wavelength, amplitude, and velocity. Reflection is discussed in terms of fixed and free ends, while refraction involves changes in media. Interference is categorized into constructive and destructive types, and standing waves are described by their nodes and antinodes.

Which of the following is NOT a characteristic of a wave that may change during a behavior?

• Frequency

• Velocity

• Color

• Amplitude

What happens to a wave pulse when it reflects off a fixed end?

• It disappears

• It doubles in amplitude

• It speeds up

• It inverts and changes direction

How does a wave pulse behave when it reflects off a free end?

• It inverts and changes direction

• It stays upright and changes direction

• It disappears

• It speeds up

When a wave moves from one medium to another, which characteristic remains constant?

• Amplitude

• Frequency

• Wavelength

• Velocity

What happens to the wavelength of a wave as it moves from a medium with longer rods to shorter rods?

• It decreases

• It remains the same

• It increases

• It disappears

In constructive interference, what is the result of two waves meeting?

• A smaller wave is formed

• The waves cancel each other out

• A larger wave is formed

• The waves stop moving

In destructive interference, what happens to the amplitude of the resulting wave?

• It remains the same

• It doubles

• It becomes zero or less than either wave

• It increases slightly

What is the term for the point of maximum vibration in a standing wave?

• Crest

• Trough

• Node

• Antinode

What is the relationship between the order number of a standing wave and the number of antinodes?

• The order number is unrelated to the number of antinodes

• The order number is double the number of antinodes

• The order number equals the number of antinodes

• The order number is half the number of antinodes

To measure the wavelength of a standing wave, what distance is multiplied by 2?

• The distance from crest to crest

• The distance from trough to trough

• The distance from node to node

• The distance from antinode to antinode
