Chapter 33: Q. 56 (page 957)

FIGURE P33.56 shows the light intensity on a screen behind a single slit. The slit width is $0.20 mm$ and the screen is $1.5 m$ behind the slit. What is the wavelength (in nm) of the light?

Short Answer

Expert verified

The wavelength of the light $667 nm$

Step by step solution

Central Fringe

Remember that the complete width of a main fringes with in the single study is given by

$w_{c} = \frac{2 λ L}{a}$

In an intellectual result, we are able to resolve parametrically just for the wavelength to search out an answer.

$λ = \frac{a w_{c}}{2 L}$

Wavelength

In terms of numbers, our wavelength are going to be

$λ = \frac{2 \times 10^{- 4} m \times 1 \times 10^{- 2} c m}{2 m m \times 1.5 m}$

$= 6 . \overset{}{6} \times 10^{- 7} m$

$= 667 nm$
