What is the wavelength of radiation with a frequency of 2.3 *10¹³ /sec? A) 3.0 * 10⁸ m B) 7.6 * 10⁵ cm C) 7.6 * 10⁵ m D) 1.3 * 10^-5 cm E) 1.3 * 10^-5 m

Question

Quizplus · Accepted Answer

We can use the equation: 
λ = c/f 
where λ is the wavelength, c is the speed of light (3.00 x 10^8 m/s), and f is the frequency. Plugging in the given values: 
λ = (3.00 x 10^8 m/s)/(2.3 x 10^10 /s) 
λ ≈ 1.3 x 10^-5 m 
which is equal to 13 µm (micro meters), or 1.3 x 10^-2 cm (centimeters), or 130 nm (nano meters). 
The closest option is E: 1.3 x 10^-5 m.
