what is the wavelength in nm of radiation having a frequency of 2.45x10^9Hz

Answer 1

Wave length=speed of light/frequecy (speed of light=3x10^8) (answer 0.000000000122nm)

Answer 2

I agree with Lorry but I would express it as 1.22E-10 nm

Answer 3

1.22^8 is the right answer

Answer 4

1.22 x 10^8 is the correct answer.
Given:
2.45 x 10^9 = frequency(v)
3.00 x 10^8 = speed of light(c)
Solution:
(3.00 x 10^8 m/s)/(2.45 x 10^9 Hz)= 1.22 x 10^8nm
