Calculate the wavelength (in nm)of the red light emitted by a neon sign with a frequency of 4.76 × 10¹⁴ Hz. A) 630 nm B) 159 nm C) 476 nm D) 776 nm E) 176 nm

Question

Quizplus · Accepted Answer

We can use the equation: 
wavelength = speed of light/frequency

The speed of light is a constant, which is approximately 3.00 x 10^8 m/s or 3.00 x 10^17 nm/s. 
Plugging in the given frequency, we get:

wavelength = (3.00 x 10^17 nm/s)/(4.76 x 10^14 Hz) 
wavelength = 630 nm

Therefore, the wavelength of the red light emitted by the neon sign is 630 nm.
