Front

Do radio waves and gamma rays travel at the same speed?

Back

Yes, they travel at the same speed.

Front

What happens to the gravitational force if the distance between two objects is quadrupled and the mass of one object is also quadrupled?

Back

The gravitational force becomes 1/4 as much.

Front

Define frequency in the context of waves.

Back

Frequency is the number of waves that pass a point in one second.

Front

What is amplitude in wave physics?

Back

Amplitude is the maximum extent of a wave's oscillation, measured from its rest position.

Front

Explain wavelength.

Back

Wavelength is the distance between successive crests of a wave.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

The speed of electromagnetic waves in a vacuum is approximately 3 x 10^8 meters per second.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with greater mass.
