Calculate the wavelength , frequency, wave no. of light whose period is 10-¹⁰ sec​

Answer 1

$\huge{\underbrace{\overbrace{\mathfrak{\pink{Answer:}}}}}$

Given period=

2.0 x 10-10s

We know, Frequency (ν) of light ,therefore putting the values .we get

We also know

where c = velocity of light in vacuum = 3×108 m/s

Substituting the value in the given expression of λ, we get
