Does increasing the frequency of a wave also increase its speed?

• Yes, always

• No, the medium determines speed

• Yes, but only in a vacuum

• No, only if the amplitude increases

• It becomes zero

• It decreases

• It increases

What remains constant when a wave changes medium and speeds up?

• Its frequency

• Its wavelength

• Its speed

• Its amplitude

How are frequency and wavelength related, assuming constant speed?

• Directly proportional

• Inversely proportional

• Not related

• Equal to each other

In the car analogy, why do shorter cars (waves) pass more frequently?

• Because they are smaller

• Because they are faster

• Because they are lighter

• Because they have shorter wavelengths
