Exploring Transverse Waves with pHET Animation

What initiates a transverse wave?

• Longitudinal vibrations

• Random vibrations

• Perpendicular vibrations

• Parallel vibrations

How is the amplitude of a wave defined?

• Distance between two crests

• Maximum vertical displacement from equilibrium

• Total energy of the wave

• Frequency of the wave

What does the wavelength of a wave represent?

• The distance between two consecutive crests

• The speed of a wave

• The time for one complete vibration

• The height of a wave

What is the relationship between period and frequency?

• They are unrelated

• They are the same

• They are inversely proportional

• They are directly proportional

How does increasing the frequency affect the wavelength?

• Makes the wavelength zero

• Increases the wavelength

• Decreases the wavelength

• Does not affect the wavelength

What remains constant when the frequency of a wave changes?

• Amplitude

• Energy

• Wavelength

• Speed

What is the wave equation?

• V = f + lambda

• V = f - lambda

• V = f / lambda

• V = f * lambda

How can the speed of a wave be altered?

• By changing the wavelength

• By changing the medium

• By changing the amplitude

• By changing the frequency

What effect does temperature have on the speed of sound in air?

• Decreases with higher temperature

• Increases with higher temperature

• No effect

• Only changes at extreme temperatures

What happens to the speed of a wave when the tension in the medium increases?

• Speed becomes zero

• Speed remains constant

• Speed decreases

• Speed increases
