What are the wavelengths for X-rays with frequency 3 × 1018?
1 × 10–10 m
3 × 10–10 m
3 × 1026 m
9 × 1026 m

Answer 1

1 x 10 ^-10 m

Explanation:

Answer 2

Answer: The wavelength for X-rays with the given frequency is
`1* 10^(-10)m`

Explanation:

To calculate the wavelength of light, we use the equation:

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

where,

`\lambda` = wavelength of the light

c = speed of light =
`3* 10^8m/s`

`\\u` = frequency of light =
`3* 10^(18)s^(-1)`

Putting the values in above equation, we get:

`\lambda=(3* 10^8m/s)/(3* 10^(19)s^(-1))=1* 10^(-10)m`

Hence, the wavelength for X-rays with the given frequency is
`1* 10^(-10)m`
