Question

define luminous and non luminous objects with eg how light travels?​

Answer 1

Answer:

Luminous objects Non-luminous objects

Objects that can emit light energy by themselves are known as luminous objects.

Objects that cannot emit light energy by themselves are known as non-luminous objects.

These objects can cause the sensation of light.

These objects do not cause the sensation of light.

The luminous objects are visible as they emit light on their own.

The non-luminous objects are visible because of luminous objects.

The sun and candle are the two examples. The moon and plants are the two examples.

Explanation:

Light travels as waves. These are transverse waves, like the ripples in a tank of water. The direction of vibration in the waves is at 90° to the direction that the light travels. Light travels in straight lines, so if you have to represent a ray of light in a drawing, always use a ruler.

Answer 2

Explanation:

1. luminous bodies give out light energy on their own. E.g- the sun,the stars,burning candle,etc
2. non luminous bodies so not give out light energy on their own but reflect the light energy falling on them. E.g- wood,houses, furniture,etc.
