Mechanical waves
Transverse waves
3.)The frequency of yellow light is 5.0 x 1014 Hz. Find the wavelength of yellow light.
6000 nm

4.)A wave generator produces 16.0 pulses in 4.00 seconds. What is its period?
4.00 s
2.50 s
0.750 s
0.250 s
5.)The velocity of a wave on a string depends on how hard the string is stretched, and on the mass per unit length of the stretch. If FT is the tension in the string, and u is the mass/unit length, then the velocity, v, can be determined.
v = sqrt(FT/u)
