<u>Answer:</u> The wavelength for X-rays with the given frequency is
<u>Step-by-step explanation:</u>
To calculate the wavelength of light, we use the equation:
where,
= wavelength of the light
c = speed of light =
= frequency of light =
Putting the values in above equation, we get:
Hence, the wavelength for X-rays with the given frequency is
We have that
<span> 5x/7=22
multiply by 7 both sides
5x=22*7-------> 5x=154
divide by 5 both sides
x=154/5
x=30.8--------> x=30 4/5
the answer is
x=30 4/5</span>
