Wavelength Calculations

Determine the wavelength of this wave?

• 1m

• 2m

• 3m

• 4m

The unit of frequency is ___.

• meters

• nanometers (nm)

• m/s

• Hertz

Which has the LONGEST wavelength and, therefore, the LOWEST frequency/energy

• Gamma Rays

• Ultraviolet

• Visible Light

• Infrared rays

Wavelength and Frequency are related in that...

• they are always the same

• when one increases, the other decreases (inversely proportional)

• there is no correlation

• they both vary in an irregular pattern
