Light does not require a medium to propogate. Ex: The rays from the sun.

The object, that allows no light to pass through, is called Opaque.

The path along which light travels in a homogeneous medium is called a ray of light

Light is an electromagnetic wave which is transverse in nature. It does not require any material medium to pass through and can travel through vacuum.

Moon does not emit its own light. It reflects the light incident on it from the Sun. So, Moon is a non-luminous body.

Light is an electromagnetic wave which is transverse in nature. So, it does not require any material medium to pass through. Light, thus, can travel through vacuum.

A green leaf can only reflect green light, so when red light is incident on it, the leaf will not be able to reflect any light making it look black
