Because Light Travels In A Straight Line And Casts A Shadow?

Because light travels in a straight line and casts a shadow, Isaac Newton hypothesized that light is.

How can a shadow help show that light travels in a straight line?

Shadows are evidence of light travelling in straight lines. An object blocks light so that it can’t reach the surface where we see the shadow. 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.

How can you show that light travels in a straight line?

Light travels in a Straight Line : School Science Project –

Why do light travels in a straight line?

Light travels in the straight line because it does not generally interact with the medium and wherever it interacts it does change its path like when it is entering a different medium with different permeability and permittivity(denser or rarer). This interaction and bending of light is called refraction.

Does light travel in a straight line or in waves?

Light surely travels in straight lines. The phenomenon is called rectilinear propagation of light. By the wave/particle duality of quantum mechanics, light can be regarded as both a wave and a particle. Under the theory that light was made up of waves, it was not clear how it would respond to gravity.Travel
