Solution
The optical media that will produce a parallel beam of light when light from an appointed source is incident on it is a concave mirror as well as a convex lens.
Here's why:
-
Concave Mirror: When parallel rays of light hit a concave mirror, they reflect and converge at a single point known as the focus. Conversely, if a light source is placed at the focus of a concave mirror, the reflected rays will be parallel to each other.
-
Convex Lens: A convex lens works in a similar way. When parallel rays of light pass through a convex lens, they refract and converge at a point known as the focus. If a light source is placed at the focus of a convex lens, the refracted rays will be parallel to each other.
Therefore, both a concave mirror and a convex lens can produce a parallel beam of light when light from an appointed source is incident on them.
