Question

488 nm light passes through a single
slit. The first (m = 1) diffraction
minimum occurs at an angle of
0.559º. What is the width of the slit?
[?] x 10-5 m

Answer 1

Answer:

5.00

Explanation:

a sinθ=mλ

You are missing (a) so you move sinθ to the other side than solve from there.

Answer 2

For first diffraction, the width of the slit is $5*10^{-5} m$.

What is diffraction?

Diffraction of light is defined as the bending of light around corners such that it spreads out and illuminates areas where a shadow is expected.

a sinθ=mλ

$a = \frac{1*488*10^{-9} }{sin 0.559}$

$a = 5*10^{-5} m$
