Class X Chapter 10 – Light - Reflection and Refraction Science
Question 1:Define the principal focus of a concave mirror.
Answer: Light rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis after reflecting from the mirror. This point is known as the principal focus of the concave mirror.
Question 2: The radius of curvature of a spherical mirror is 20 cm. What is its focal length?
Answer: Radius of curvature, R = 20 cm Radius of curvature of a spherical mirror = 2 × Focal length (f)
R = 2f Hence, the focal length of the given spherical mirror is 10 cm.
Question 3: Name the mirror that can give an erect and enlarged image of an object.
Answer: When an object is placed between the pole and the principal focus of a concave mirror, the image formed is virtual, erect, and enlarged.
Question 4: Why do we prefer a convex mirror as a rear-view mirror in vehicles?
