We know that the Relation between Frequency and Wavelength of an EMR is given by :
[tex]\heartsuit[/tex] 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
[tex]\implies \nu = \frac{3\times10^8}{10^-^1^0}[/tex]
⇒ ν = 3 × 10¹⁸ sec⁻¹
So, The Frequency of the Given EMR is 3 × 10¹⁸ sec⁻¹
