Question

In the experiment of diffraction at a single slit,

if the slit width is decreased, the width of the

central maximum

a)Increases in both Fresnel and Fraunhoffer

diffraction

b)Decreases both in Fresnal and Fraunhoffer

diffraction

c)Increases in Fresnel diffraction but

decreases in Fraunhoffer diffraction

d)Decreases in Fresnel diffraction but

increases in Fraunhoffer diffraction​

Answer 1

Explanation:

note that the width of the central diffraction maximum is inversely proportional to the width of the slit. If we increase the width size, a, the angle T at which the intensity first becomes zero decreases, resulting in a narrower central band.

Answer 2

Answer:

hello

Explanation:

a)Increases in both Fresnel and Fraunhoffer

diffraction
