Question

calculate the frequency of yellow light of wavelength 550nm . the speed of light is 3*10^8 m/sec

Answer 1

Answer:

u=c/lamda

u=3*10^8/55*10^-8

=3/55*10^16

=0.0545*10^16

=545*10^12 Herz

is the frequency....

Answer 2

Answer : 54*10^14 Hz

Explanation:

Given :

Wavelength of yellow light (w) = 550 nm

Speed of light (c) = 3*10^8

We have,

Speed of light = wavelength * frequency

frequency (f) = c/w

=> f = 3*10^8/550*10^-9

=> f = 0.0054 * 10^17

=> f = 54*10^14 Hz

Frequency of yellow light = 54 * 10^14 Hz
