Answer 2

Calculating Distance Between Maxima

To calculate the distance between the zeroth and first-order maxima for a diffraction grating, we can use the formula:

d*sin(θ) = m*λ

Where: - d is the period of the diffraction grating - θ is the angle of diffraction - m is the order of the maximum - λ is the wavelength of the incident light

Given: - Period of the diffraction grating, d = 0.02 mm = 0.02 × 10^-3 m - Distance from the grating to the screen, L = 2 m - Wavelength of the incident light, λ = 600 nm = 600 × 10^-9 m - We are interested in the distance between the zeroth and first-order maxima, so m = 1

First, we need to find the angle of diffraction, θ, using the formula:

sin(θ) = m*λ / d

Let's calculate θ using the given values.
