Question

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

Answer 1

555.56 nm

Step-by-step 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* 10^8\ m/s}{5.4* 10^(14)\ s^(-1)}`

Wavelength = 555.56×10⁻⁹ m

1 nm = 10⁻⁹ m

So, wavelength = 555.56 nm
