frequency of a radiation having wavelength 3200A

​

Answer 1

$\huge\underline{\overline{\mid{\bold{\pink{ANSWER-}}\mid}}}$

e=hc/wavelenth

=6.626*10-34*3*108/3000*10 -10

=0.006626 *10 -16

=6.626*10 -19 j

and frequency=3 *108/3000*10 -10

=0.001*1018

Answer 2

Answer:

Electromagnetic waves travel at the speed of light (299,792,458 meters per second) and their frequency and wavelength can be determined by the formulas:

Explanation:

'f' is a freaquenc in cycle per sec

'c' is the light velocity (299,792,458 meters per second)
