Consider the equation for constructive interference for a double-slit:
, where d is the distance between the slits, θ is the angle between the path and a line from the slits to the screen, m is the order of interference, and λ is the wavelength of the light.
For destructive interference:
The maximum occurs as a result of constructive interference.
We substitute m = 1 for the first-order maximum.
Suppose the first-order maximum for monochromatic light falling on a double slit is at an angle of 9.5°.
A. At what angle (in degrees) is the second-order maximum?
B. What is angle (in degrees) of the first minimum?
