How is wavelength measured?

• Wavelength is measuring the distance between the highest point and the lowest point of the wave

• Wavelength is measuring the distance from the beginning of the wave to the very end of the wave

• Wavelength is measuring the distance between two similar parts of a wave.

• Wavelength is the distance between resting point and the highest point of a wave

What is wave frequency

• How high the wave gets

• How low the wave gets

• The number of waves that happen in a certain amount of time

• The distance between the highest point of a wave and its resting point

Which of the following best represent an example of electromagnetic radiation

• An ocean wave crashing on the beach

• a series of waves going on direction and a rogue wave going the opposite

• Wind blowing your hair around

• Sunlight shining on a lake
