200

frequency is measured in units called Hertz(Hz)

What unit is frequency measured on?

200
Are light waves longitudinal or transverse? 

Light waves are transverse waves.

300
the number of complete waves that pass a given point in a certain amount of time
What is frequency?
300

How are wavelength and frequency related? 

Inversely, if one goes up, the other goes down. 

300

How does frequency affect pitch? 

Higher frequency, higher pitch.

How are the energy of a wave and the amplitude of a wave related?

The higher the amplitude, the more energy the wave has and vice versa.

500

What is the mathematical relationship between energy and amplitude of a wave?

The energy of a wave is proportional to the square of the amplitude. 

500

How do you find the wavelength of a wave? (FORMULA) - rearrange 

 Wavelength = Wave speed (V) / Frequency (F)
