Question

1. Calculate the
frequency of
light having a
wavelength of
4500 Ao?​

Answer 1

"Answer:

6.67 x 10^14 Hz

Explanation:

frequency = speed of light / wavelength

                 = (3 x 10^8) / (4.5 x 10^-7)

                 = (30 x 10^15 ) / 45

                 = 2/3 x 10^15

                 = 6.67 x 10^14 Hz
