What is the frequency of radiation whose wavelength is 2.40x10-5cm?

Answer 1

This problem can be solved using the equation

c = freq x wavelength, where c is the speed of light, which is 3.00 x 10^8 m / s

freq = c / wavelength

freq = (3.00 x 10^8m /s) / (2.40 x 10^-5 cm x 1 m /100cm)

freq = (3.00 x 10^8 m/s) / 2.40 x 10^-7m

freq = 1.25 x 10^15/s 1 / s = 1Hz

freq = 1.25 x 10^15Hz

Answer 2

Frequency = speed/wavelength

Assume that we're talking about free space/vacuum, so the speed of the wave is about 300,000 km/sec.

Frequency = 3 x 108 / 2.3 x 10-9 = 1.3043 x 1017 = 130,430,000 GHz. (rounded)

Answer 3

frequency= speed of light/lambda

3.00x10^8/10.5x10^-10=2.86x10^17

Answer 4

C=fλ rearranges to f=C/λ

f= 3 x 108 / 0.955 x 10-6

f= 3.14 x 1014Hz

Answer 5

510 THz

5.09 x 1012 Hz

Assuming the speed of light is 3.00 x 108 m/s ie in a vacuum

Answer 6

Wavelength = speed/frequency = 3 x 108/2.12 x 1020 = 1.415 x 10-12 meter = 0.0014 nanometer
