What is the frequency of light that has a wavelength of 4.25 x 10-8 meters meters?

Answer 1

Since, frequency, f = c / λ

Then, λ = 405 x 10-6 cm = 4.05 x 10-10 m

Speed of light c = 299,792,458 m/s

Therefore, frequency f = 299,792,458 m/s / 4.05 x 10-10 m = 740,228,291,358,024,691 Hz = 7.40 x 1017 Hertz.

Answer 2

speed of light = wavelength(m) X frequency (^-s)

Speed of light in a vacuum is 3.0 x 10^-8 ms^-1

Wavelength = 5.23 x 10^-7 m

Hence frequency(^-s) = speed of Light (ms^-1) / wavelength (m)

Hence frequency = 3.0 x 10^8 ms^-1 / 5.23 x 10^-7 m

frequency (^s-1) = 5.74 x10^(14) (^s-1)

NB This unit is naned Hertz (Hz)

Hence

frequency = 5.74 x 10^(14) Hz.

Answer 3

The frequency of light can be calculated using the formula: frequency = speed of light / wavelength. Given that the speed of light is approximately 3.00 x 10^8 meters per second, the frequency of light with a wavelength of 4.25 x 10^-8 meters would be approximately 7.06 x 10^15 Hz.

Answer 4

Frequency = speed / wavelength = 3 x 108/4.5 x 10-4 = 62/3 x 1011 Hz = 6662/3 GHz

Answer 5

For any wave, (speed) = (wavelength) x (frequency). So, just divide the speed of light - about 300 x 10^6 (m/s)- by the wavelength.

Answer 6

4.25 x 10^-8 m

Answer 7

27.759 MHz
