Do light always travel in a straight line?
Any physics student knows that light travels in a straight line. But now researchers have shown that light can also travel in a curve, without any external influence. The effect is actually an optical illusion, although the researchers say it could have practical uses such as moving objects with light from afar.
How do you prove that light travels in a straight line?

Why does light travel in straight lines Wikipedia?
When one of the cardboard is slightly displaced, candle light would not be visible. It means that the light emitted by the candle is unable to bend and reach observers eye. This proves that light travels along a straight path. This proves the rectilinear propagation of light.
How does a light travel class6?
Shadows are formed because light rays travels in a straight line, and they cannot bend round the corners of the objects. The shape of the shadow is also the same as the shape of the object because light travels in a straight line path.
What is light short answer?
Light is a form of energy with which a human eye makes the things visible. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun. Light contains photons which are minute packets of energy.
How does the light travel?
Light can travel in three ways from a source to another location: (1) directly from the source through empty space; (2) through various media; (3) after being reflected from a mirror.
