True False
2) True or false ? Wavelength is the distance between one trough to the next crest of the next wave.
3) True or false ? Frequency is the number of waves that pass by at a point each second.
4) True or false ? Shorter wavelength means greater frequency for a wave.
5) True or false ? The closer you get to a light souce, the less intensity it has.
