All but two gaps within a set of Venetian blinds have been blocked off to create a double-slit system. These gaps are separated by a distance of 5.0 cm. Infrared radiation is then passed through the two gaps in the blinds. If the angle between the central and the second-order maxima in the interference pattern is 0.52°, what is the wavelength of the radiation?

Respuesta :

Answer:

Explanation:

separation between two gaps, d = 5 cm

angle between central and second order maxima, θ = 0.52°

use

d Sinθ = n λ

n = 2

0.05 x Sin 0.52° = 2 x λ

λ = 2.27 x 10^-4 m

λ = 226.9 micro metre
