Write whether of the following objects are luminous or non-luminous. Object Luminous/ Non-luminous A book A burning candle A wax cloth A pencil A pen A light bulb A tyre A torch

Objects that can produce their own light are called luminous object and object that cannot produce the light on their own are called non-luminous. Object Luminous/Non-luminous A book Non-luminous A burning candle Luminous A wax cloth Non-luminous A pencil Non-luminous A pen Non-luminous A light bulb Luminous A tyre Non-luminous A torch Luminous

Match the following. Group A Group B (a) Mirror (1) Non-luminous (b) Firefly (2) Inverted image (c) Pinhole camera (3) Reflection (d) Moon (4) Luminous

(a) Mirror - (3) Reflection The mirror is a silver polished and smooth surface of the glass which forms images by reflection. (b) Firefly - (4) Luminous Firefly is a luminous creature as it produces its own light. (c) Pinhole camera - (2) Inverted image A pinhole camera makes an inverted image, it is a simple camera that does not have a lens but has a tiny aperture. The rectilinear propagation of light is responsible for the inverted image. (d) Moon - (1) Non-luminous Moon is a non-luminous object. It does not produce any light. It only reflects the light coming from the Sun. Group A Group B (a) Mirror (3) Reflection (b) Firefly (4) Luminous (c) Pinhole camera (2) Inverted image (d) Moon (1) Non-luminous

Shadow is nothing but a dark area formed when the light gets blocked by an opaque object. The rectilinear propagation of light is responsible for making the shadow. A transparent or translucent object cannot form a shadow.
