# Explain Why the Maxima Become Weaker and Weaker with Increasing N - Physics

Explain why the maxima at theta=(n+1/2)lambda/a become weaker and weaker with increasing n

#### Solution

On increasing the value of n, the part of slit contributing to the maximum decreases. Hence, the maximum becomes weaker.
