Answer:

the angle, in radians, between the central maximum = 2.87degree or 0.05radians

Explanation:

The detailed steps and appropriate formula is as shown in the attachment.

Using λm = dsin teta

where d =20λ, m = 1

from the formula, sin teta = λ/20λ

= sin teta = 0.05

teta = arc sin(0.05) = 2.87 degree
