Complete the table to determine if wavelength varies inversely with frequency. let k be the product of wavelength and frequency.

type of radiation wavelength (m) frequency (1⁄sec) k
x–rays 1 × 10−10 3 × 1018 a
radio waves 1 × 10−1 3 × 109 b
green light 600 × 10−6 5 × 1011 c
uv rays 4 × 10−7 7.5 × 1014 d
a = ×108m ⁄ s;  b = ×108m ⁄ s;  c = ×108m ⁄ s;  d = ×108m ⁄ s

the wavelength x = vary inversely with frequency.
