Question

1. If a is the width of the slits and b the
distance between the slits, then a + b is
called as​

Answer 1

Answer:

Hiii heres ur answer

Explanation:

The separation between the slits is 1. 0 m m. The intensity of microwave is measured on a screen placed parallel to the plane of the slits at a distance of 1. 0 m from it as shown in figure.

Answer 2

Answer:

If a is the width of the slits and b is the distance between the slits, then the sum of a + b is called ​ the grating constant.

Explanation:

• A diffraction grating is an optical component that separates (disperses) light made up of a variety of wavelengths (such as white light) into its individual wavelength components. The most basic kind of grating has a lot of parallel slits that are widely separated from one another.
• The grating constant for a diffraction grating is the number of lines (or slits) per unit length (eg lines per cm). As a result, the grating lines are spaced apart by the grating constant, or 1. The definition states that the grating constant, d = a + b; d is sometimes referred to as the grating element.
• It can also be defined as the distance between two neighbouring transparencies' corresponding points.
• Grating constant (a+b) = 1/N where N = number of lines

Thus, If a is the width of the slits and b is the distance between the slits, then a + b is called the grating constant.
