A magnifying glass is a common tool used to make objects appear larger. It uses a convex lens to magnify objects.

• When you raise your left hand in front of a mirror, your image raises its right hand.

When you look at yourself in a mirror, the image you see is actually the same size as you! It's not smaller.

The line drawn perpendicular to the reflecting surface at the point of incidence is called the normal. This concept is crucial in understanding the behaviour of light during reflection.

False.

Light travels in a straight line, not along a curved line. This is the principle of rectilinear propagation of light

When light passes through a prism, it splits into different colours, typically seen as red, orange, yellow, green, blue, indigo, and violet.
