Question

Let x = wavelength and y = frequency. The equation that models the inverse relation is

Answer 1

The Answer is D y= x/3x10squareroot8 m/s

Because its right on edg

Answer 2

y = (3 × 10^8 m/s)/x

Explanation:

Speed of a wave is given by the product of wavelength and frequency.

Thus; speed = frequency × wavelength

If x = wavelength and y = frequency then speed will be;

speed = yx

Thus to get wavelength, y;

y = speed/x , but speed is 3 × 10^8 m/s

Thus;

y = (3 × 10^8 m/s)/x
