Question

When a wave of light strikes a diffraction screen (or grating) it will cause the wave to pass through each slit, causing the emerging light to radiate outward as if from a new source. These newly formed waves create alternating patterns of constructive and destructive interference, which can be observed when projected onto a screen. Select the variables listed below that determine the angle at which these patterns occur (you might need to select more than one answer):

Answer 1

Answer:

The answer is "the angle depends on wavelength and distance of slits".

Explanation:

$d \sin \theta = m\lambda$  as well as angular, of mth order darkened border is indicated only by angular position, the $\theta$ mth order bright border generated by a light wavelength $\lambda$ , and use the grating of the segregation slit.

$d \sin \theta = ( m + \frac{1}{2}) \lambda$

Therefore, $\theta$ depends on d and $\lambda$ for a specific order.
