Question

(Figure 1) shows the light intensity on a viewing screen behind a single slit of width a. The light's wavelength is ?.

Is ?<a, ?=a, ?>a, or is it not possible to tell?

Drag the terms on the left to the appropriate blanks on the right to complete the sentences.

Reset Help The width of the central maximum in the intensity pattern for a single slit is given by | If λ > a then w will be equal to or | It is obvious that w 《 2L, hence λ is equal to 2L a. greater than less than

Answer 1

1) w = 2*L*lamda/a

we know, widht of central maximum = 2*lamda*R/d

lamda --> wavelength

R ---> distance between slit and screen

d is slit width.

2) greater than

3) less than
