A spherical mirror and a thin spherical lens have each a focal length ...
Introduction:
This question pertains to the properties of a spherical mirror and a thin spherical lens, both of which have a focal length of -12 cm. The aim is to determine the likely characteristics of the mirror and the lens based on their focal lengths.
Explanation:
To determine the characteristics of the mirror and the lens, we need to understand the behavior of concave and convex mirrors and lenses.
Concave Mirror:
- A concave mirror is curved inward, like the inner surface of a spoon.
- It converges incident light rays towards a focal point.
- The focal length of a concave mirror is positive.
Convex Mirror:
- A convex mirror is curved outward, like the outer surface of a spoon.
- It diverges incident light rays, causing them to spread out.
- The focal length of a convex mirror is negative.
Concave Lens:
- A concave lens is thinner at the center and thicker at the edges.
- It diverges incident light rays, causing them to spread out.
- The focal length of a concave lens is positive.
Convex Lens:
- A convex lens is thicker at the center and thinner at the edges.
- It converges incident light rays towards a focal point.
- The focal length of a convex lens is positive.
Given Information:
- Both the mirror and the lens have a focal length of -12 cm.
Analysis:
Based on the given information and the characteristics of mirrors and lenses, we can conclude that:
- A focal length of -12 cm indicates that the mirror and the lens both have a negative focal length.
- A negative focal length is associated with diverging properties, which are exhibited by convex mirrors and concave lenses.
Conclusion:
Therefore, the correct answer is option 'D': Both the mirror and the lens are concave.
