Both concave and convex mirror send the reflected light at the same angle as the angle of incidence on the other side of the principal axis. [True/ False]
Answer
True. Explanation:
The normal line divides the angle between the incident ray and the reflected ray into two equal angles. The angle between the incident ray and the normal is known as the angle of incidence.
A convex mirror of focal length 'f' produces an image $\frac{1}{\text{m}}$ of the size of object, then object distance is (m - 1)f numerically. [True/ False]
Answer
True. Explanation:
The focal length of a concave mirror, with a real focus, is always positive, and the focal length of a convex mirror, with a virtual focus, is always negative.
Convex mirror and convex lens always form virtualimage. [True/ False]
Answer
True. Explanation:
A convex mirror forms only virtual, diminished and erect images for all positions of the object, whereas a convex lens can form both real, inverted images of various sizes and virtual, erect and enlarged images depending on the position of the object.
State whether the following statement is true or false:
A student says that we can see an object because light from our eyes is reflected back by the object
Convex mirror and convex lens always form virtual image. [True/ False]
Answer
True. Explanation:
A convex mirror forms only virtual, diminished and erect images for all positions of the object, whereas a convex lens can form both real, inverted images of various sizes and virtual, erect and enlarged images depending on the position of the object.
