State whether true or false.
The moon is a luminous body.
Solution
Objects that are capable of giving out light by themselves are called luminous objects. Objects that do not emit light of their own are called non-luminous objects.
Complete step by step answer:
Objects that are capable of giving out light by themselves are called luminous objects. Luminous objects have their own source of energy. These can be natural or artificial. The sun and the stars are natural luminous objects.
Objects that do not emit light of their own are called non-luminous objects. Non-luminous objects become visible when they reflect some of the light that falls on them from a luminous source, which then enters our eyes. Most of the objects we see around us are non-luminous
objects; they just reflect light from the sun or from artificial sources. For example, furniture, stones and books are non-luminous objects. Even the moon, which appears as a bright object in the night sky, is a non-luminous object. The moon receives light from the sun and reflects it as moonlight. This moonlight reaches us on the earth, enabling us to see the moon.
So, the correct answer is “FALSE”.
Note:
We need light to see the world around us. It makes things visible to us. Light is a form of energy that causes the sensation of vision and helps us to see objects. For an object to be visible, light from a source has to fall on it, bounce back from its surface and then enter our eyes.
