Question

Find the wavelength in nanometers of visible light of frequency 5.4×10^14 Hz.

Answer 1

Answer:

555.56 nm

Explanation:

The relation between frequency and wavelength is shown below as:

c = frequency × Wavelength

Where, c is the speed of light having value = 3×10⁸ m/s

Given  that: Frequency = 5.4×10¹⁴ Hz

So, Wavelength is:

Wavelength = c / Frequency  

$Wavelength=\frac {3\times 10^8\ m/s}{5.4\times 10^{14}\ s^{-1}}$

Wavelength = 555.56×10⁻⁹ m

1 nm = 10⁻⁹ m

So, wavelength = 555.56 nm
