Question

At what angle is the first minimum for 550-nm light falling on a single slit of width 1.00μm?

a) 0.26 degrees
b) 0.53 degrees
c) 1.06 degrees
d) 2.12 degrees

Answer 1

The angle of the first minimum for 550-nm light falling on a single slit of width 1.00 μm is 0.26 degrees.

Step-by-step explanation:

To find the angle of the first minimum for 550-nm light falling on a single slit of width 1.00 μm, we can use the formula:

θ = λ / (2 * a)

where θ is the angle, λ is the wavelength, and a is the slit width. Plugging in the values, we get:

θ = (550 nm) / (2 * 1.00 μm) = 0.275 radians

Converting radians to degrees, the angle is approximately 0.26 degrees. Therefore, option a) 0.26 degrees is the correct answer.
