d. the number of waves that pass one point in a certain amount of time
What is amplitude? a. a wave with long wavelengths b. a wave with short wavelengths c. the height of a wave from rest position d. the volume of a wave from rest position
c. the height of a wave from rest position
If the frequency of a wave increases, what happens to its wavelength? a. Its wavelength increases. b. Its wavelength decreases. c. Its wavelength stops moving. d. Its wavelength vibrates in place.
b. its wavelength decreases
T or F. The shorter the wavelength, the higher the amplitude. The higher the amplitude, the higher the frequency. The higher the frequency, the more energy the wave has. Therefore, the shorter the wavelength, the more energy the wave has
True
What are gamma rays like? a. They have long wavelengths and low energy. b. They have short wavelengths and low energy. c. They have long wavelengths and high energy. d. They have short wavelengths and high energy
d. They have short wavelengths and high energy
Open response: Why is there no sound in space?
There is no matter in space. Sound waves need matter to travel through.
Open Response: Scientists determine the amount of energy in a wave by looking at two measurements.
