Question

light travels in which direction​

Answer 1

Answer:

Light waves travel out from their source in straight lines called rays. Rays do not curve around corners, so when they hit an opaque object (one that does not allow light to pass through it), they are blocked from reaching the other side of that object.

Answer 2

Answer:

Light travels in straight lines

Light fills up all of the space before it hits the object, but the whole region between the object and the surface is in shadow.

Explanation:

Light propagates as electromagnetic waves. Light can travel in all all directions as light waves are spherical waves which travel radially outwards from its source.
