1st Semester Spiral Review #1

Front

How are frequency and pitch related?

Back

The higher the frequency, the higher the pitch.

Front

Which type of wave has the SHORTEST wavelength and the highest frequency?

Back

Gamma Rays.

Front

What happens to the pull of gravity as the distance between two objects increases?

Back

The pull of gravity decreases.

Front

What does the Hertzsprung-Russell diagram show about main-sequence stars?

Back

Main-sequence stars increase in brightness as they increase in temperature.

Front

In what type of wave does the medium vibrate parallel to the direction of the wave?

Back

Longitudinal wave.

Front

Define frequency in the context of waves.

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases.

Front

What type of wave is a sound wave?

Back

Sound waves are longitudinal waves.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.

Front

What is the significance of the speed of light in physics?

Back

The speed of light is a fundamental constant that represents the maximum speed at which information and matter can travel.
