The wavelength of light that has a frequency of 1.20 × 1013s-1 is __________ m.
25.0
2.50 × 10-5
0.0400
12.0
The speed of all form of electromagnetic wave is related by the equation c = λ.v, whereby, λ = 3.0 x 108 / 1.2 x 1013 = 2.5 x 10 -5 m.
What is the wavelength of light (nm) that has a frequency of 4.62 ×1014s-1?
a. 932
b. 649
c. 1.54 × 10-3
d.1.07 × 106
