If an x-ray machine emits e. m.r with a wavelength of 1.00 x 10^-10 meters, what is the frequency?

We know that the Relation between Frequency and Wavelength of an EMR is given by :

 c = νλ

where 'c' is the Velocity of the Light in Vacuum which is 3 × 10⁸ Meter/sec

'ν' is the Frequency of EMR

'λ' is the Wavelength of EMR

Given Wavelength of the EMR = 10⁻¹⁰ Meter

Substituting all the Values in the Given Relation We Get :

⇒ 3 × 10⁸ = ν × 10⁻¹⁰

⇒ ν = 3 × 10¹⁸ sec⁻¹

So, The Frequency of the Given EMR is 3 × 10¹⁸ sec⁻¹

particle   p is an electron and particle q is a neutron

50.23 i believe is correct but don't quote me on that.
