Question

Determine the frequency of light with a wavelength of 4.27 * 10^-7

Answer 1

Answer:

$f=7.02*10^15$

Explanation:

We are supposed to find the frequency of light .

λf=c

the abow formula is the relation for frequency and wavelength.

Here c is the speed of light.

$c=3*10^9m/s$

Given that

λ= $4.27 * 10^-7$

by substituting all this we get f as,

$f=\frac{3*10^9}{4.27 * 10^-7}$

$f=7.02*10^15$
