When blue light of wavelength 470 nm falls on a single slit, the first dark bands on either side of center are separated by 51.0 ? . determine the width of the slit. express your answer to three significant figures and include the appropriate units.

The width of the slit is .

Explanation:

Given that,

Wavelength = 470 nm

Angle = 51.0°

We need to calculate the width of slit

Using formula of width

Where, n = number of fringe

= wavelength

Put the value into the formula

Hence, The width of the slit is .
