Question

The wavelength of a specific photon in the x-ray is 5 x 10-9 meters. Given that the speed of light is 2.998 x 108 m/s, what would be the frequency of this x-ray? 14.99 x 10-1 HZ 0.5996 x 10-17 HZ 1.499 x 10-2 HZ 0.5996 x 1017 HZ 1.499 x 10-4 HZ

Answer 1

f = 0.5996x10^17 Hz.

Answer = D

Answer 2

Answer : The frequency of the x-ray is,
`0.5996* 10^(17)Hz`

Explanation :

Formula used :

`\\u=(c)/(\lambda)`

where,

`\\u` = frequency of the x-ray = ?

c = speed of light =
`2.998* 10^8m/s`

`\lambda` =
`5* 10^(-9)m`

Now put all the given values in the above formula, we get the frequency of the x-ray.

`\\u=(2.998* 10^8m/s)/(5* 10^(-9)m)=0.5996* 10^(17)s^(-1)=0.5996* 10^(17)Hz`

Therefore, the frequency of the x-ray is,
`0.5996* 10^(17)Hz`
