If the speed of gravity waves is the same a for light (3.00 * 10⁸ m/s),as is thought to be the case,find the fundamental frequency of waves that would be detected by LIGO (distance between the two end points is 3002 km). A)50 Hz B)100 Hz C)200 Hz D)900 Hz E)Gravity waves,unlike electromagnetic waves,do not have a frequency.

Question

Quizplus · Accepted Answer

The fundamental frequency of a wave is given by the speed of the wave divided by the wavelength. The wavelength of a wave is twice the distance between the two end points of the detector. Therefore, the fundamental frequency of a wave that would be detected by LIGO is:f = c / (2L) = (3.00 * 10^8 m/s) / (2 * 3002 km) = 50 Hz
