In a lab, you perform a double slit experiment to measure the wavelength of a particular laser. When aimed at two slits spaced b
bekas [8.4K]

Answer:

The wavelength of the laser light is 572 nm.

Explanation:

Given that,

Distance between slit d= 0.22 mm

Distance of screen D= 0.5 m

Bright lines = 10

Width y= 1.3 cm

We need to calculate the wavelength

Using formula of young

y=\dfrac{n\lambda D}{d}

\lambda=\dfrac{dy}{nD}

Put the value into the formula

\lambda=\dfrac{0.22\times10^{-3}\times1.3\times10^{-2}}{10\times0.5}

\lambda=5.72\times10^{-7}\ m

\lambda=572\times10^{-9}\ m

Hence, The wavelength of the laser light is 572 nm.
