Question

(i) Name one factor that affects the lateral displacement of light as it passes through a rectangular glass slab.
(ii) On reversing the direction of the current in a wire, the magnetic field produced by it gets.

Answer 1

Hint:Light, also known as visible light, is electromagnetic radiation that falls within the part of the electromagnetic spectrum that the human eye can detect. Between the infrared and ultraviolet, visible light is classified as having wavelengths in the 400–700 nm range.

Complete answer:
(i) The outline of a glass slab is cuboidal (opposite surfaces parallel to each other). Second, let's look at what happens when a beam of light hits a glass slab. When a light ray travels through two adjacent faces of a glass slab, it is refracted twice. Finally, it appears parallel to the course of the event. Assume a light ray from the air hits the glass slab. This is where it can first be refracted.

The following considerations influence a light's lateral displacement when it travels through a rectangular glass slab:
-The width of the glass slab: As the thickness of the glass slab grows, so does the lateral displacement.
-The angle of incidence: As the angle of incidence increases, it increases.
-Glass's refractive index: The light wavelength that was used. (It affects violet light rather than red light.)

(ii) The magnetic field is the region surrounding the magnetic force that is applied. It's made by shifting electric charges around. Lines represent the orientation of the magnetic field. Electric fields are generated around the particles that acquire electric charge. When you loop your right hand around a current-carrying wire with your thumb in the direction of current, the magnetic field is perpendicular to the wire and in the direction your fingers curl. As a result, reversing the current reverses the magnetic field's orientation.

Note:Since a shifting electromagnetic field produces a magnetic field, and a changing magnetic field creates an electric field, electricity and magnetism are exactly the same thing. (Physicists typically refer to "electromagnetism" or "electromagnetic" forces as a group rather than individually.)
