Wave Properties and Interactions

What is a wave primarily defined as?

• A stationary energy form

• A static object in space

• A disturbance that moves through space and time

• A solid object that vibrates

Which type of wave moves perpendicular to the direction of motion?

• Longitudinal wave

• Transverse wave

• Radio wave

• Sound wave

In a longitudinal wave, how do the particles oscillate?

• In the direction of the motion

• Randomly

• In a circular motion

• Perpendicular to the motion

What is the formula for wave speed?

• V = Lambda / F

• V = F / Lambda

• V = F + Lambda

• V = F * Lambda

What does the term 'frequency' refer to in wave properties?

• The height of the wave

• The speed of the wave

• How often waves occur

• The length of the wave

What happens to the wavelength if the frequency of a wave increases?

• The wavelength increases

• The wavelength doubles

• The wavelength decreases

• The wavelength remains the same

What is the term for waves bending around a small opening?

• Reflection

• Refraction

• Diffraction

• Absorption

Which type of wave interaction involves a wave bouncing back from a surface?

• Reflection

• Refraction

• Diffraction

• Absorption

Why do low-frequency sounds bend more easily around obstacles?

• They travel faster

• They are louder

• They have higher energy

• They have longer wavelengths

How fast can a tsunami wave travel with a wavelength of 210 km and a frequency of 0.067 Hz?
