When red light illuminates a grating with 5000 lines per centimeter, its forth maximum (m=4) is at 47.2°. What is the wavelength of this light in nanometers?
Question
Solution 1
To solve this problem, we can use the grating equation which is given by:
dsin(θ) = mλ
where:
- d is the distance between the lines in the grating
- θ is the angle of the maximum
- m is the order of the maximum
- λ is the wavelength of the light
