The wavelength (w) of a wave varies inversely as its frequency (f). a wave with a frequency of 600 khz (kilohertz) has a length of 129 m. what is the length of a wave with a frequency of 300 khz?

The wavelength of a wave varies inversely as its frequency, i.e.

W ∝ 1/F

A wave decreases its frequency from 600kHz to 300kHz, so let's calculate the scaling factor of W due to the change in F.

k = 1/(300/600) = 2

To find the new wavelength, multiply the original wavelength by k:

W = 2×129m

W = 258m

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
