• A. Light is a form of energy.
• B. Light travels in a straight line.

Answer 1

Answer: (A), (B), (C)

The correct options are
A

Light is a form of energy.

B

Light travels in a straight line.

C

Light can travel through vacuum.

The light rays from the sun reach the earth. Since the outer space is essentially vacuum, we can say that light can travel through vacuum. Light is a form of energy which can be harnessed to generate other forms of energy as in the case of solar cells. Also, as light forms shadows of objects that come in its path, we can say that it travels in a straight line and not in a curved path.
