Light Wave Properties

What is the relationship between frequency and wavelength?

• high frequency --> short wavelength

• high frequency --> long wavelength

• low frequency --> short wavelength

• there is no relationship

• yellow

• green

• blue

Of the visible spectrum, what color has the highest frequency?

Why are Astronomers soo concerned with understanding "light"?

• They can't read in the dark

• Better than being heavy

• Because they are very smart

• Because the only way we can interact with most things is by "looking" at them

A police department just purchased new lights for their cars. Each light bulb is the same brightness. Which statement is true about the lights?

• The lights have the same amplitude, but different frequencies.

• The lights have the same amplitude, and the same frequencies.

• The lights have the different amplitudes, but the same frequencies.

• The lights have the different amplitudes and different frequencies.

Which wave has the longest wavelength?

• A

• B

• C

• None (same wavelength)
