Refraction Through Glass Slab || Lens Concave Convex With Ray Dliagram

A ray of light after refraction through a concave lens becomes parallel to the principal axis after refraction through the concave lens. Explain with a ray diagram when this can happen.

A ray of light after reflection through a concave lens becomes parallel to the principal axis after refraction through the concave lens. Wxplain with a ray diagram when this can happen.

Complete the following ray diagram to show refraction of light through a glass slab and label the incident ray, refracted ray and emergent ray.

Four students A, B, C and D selected the following items from the materials available in the science laboratory to perform an experiment to study the refraction of light through a glass slab : (A) convex lens, glass slab, pins, drawing board, white paper, scale (B) glass slab, pins, drawing board, scale, white paper, protractor (C) glass slab, glass prism, candle, screen, pins, scale, drawing board, protractor (D) concave mirror, pins, glass slab, protractor, white paper, drawing board Correct choice of the items required is made by the student :

In refraction of light through a glass slab , the directions of the incident ray and the refracted ray are "…..............."

Concave lens and Convex lens

During refraction of light through the glass slab, incident ray and emergent ray are perpendicular to each other. True/false

'During refraction of light through the glass slab, incident ray and emergent ray are parallel to each other.' Explain.
