How Does Light Travel Grade 4 . Since diffraction is very small effect, light is generally assumed to travel in straight line. When a light wave with a single frequency strikes an object, a number of things could happen.

Sound can be reflected (bounce). Light from the sun helps plants grow and makes food for us to enjoy. If you have ever worn a hat on a sunny day, you have tested this idea.

Light travels in a straight line from its source. The light wave could be absorbed by the object, in which case its energy is converted to heat. 2) when a starting pistol is fired we see the smoke first and then hear the bang. Light reflects off objects and allows us to see.

This effect is commonly reffered to as diffraction. Light bulbs can also transfer energy, just like in the video when the light bulb’s energy powered the singing fish. A reflection occurs when light rays bounce off a surface, such as when you see your reflection in a mirror. Refraction is when light bends moving from one medium to another. Light.

However, light can change its path (away from a straight line) when it is incident on certain obstacles. Light behaves like a wave and a particle. Light travels in straight lines primarily due to the fact that light is a wave. Light reflects off objects and allows us to see. Red light has the longest wavelength, and the lowest frequency.
