A uniform ladder is 10 m long and weighs 400 n. it rests with its upper end against a frictionless vertical wall. its lower end
rests on the ground and is prevented from slipping by a peg driven into the ground. the ladder makes a 30◦ angle with the horizontal. the magnitude of the force exerted on the peg by the ladder is:

We will determine the wavelength through the relationship given by the distance between slits, this relationship is given under the function
Here,
m = Number of order bright fringe
= Wavelength
d = Distance between slits
Both distance are the same, then
Rearranging to find the second wavelength
Therefore the wavelength of the light coming from the second monochromatic light source is 550.3nm
