See the table made based on the given values.
It is easy to note that the numbers in the distance column are same as numbers in the a - b column but all numbers being positive.
<u>So we can say that: </u>
Correct choice is C
<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
