Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles unlike specular reflection which is just one angle.

Specular Reflection:

- Specular reflection is a mirror-like reflection of light from a shiny, glossy or mirror surface. It is reflected from the smooth surface at a definite angle (reflection and angle are equal). The light will reflect from one single incoming direction into a single outgoing direction.

In the example above, the waves act as a mirror, so when the light hits the surface the mountain is reflected back onto the surface.

Specular reflection is also known as regular reflection, is the mirror-like reflection of waves, such as light, from a surface. In this process, each incident ray is reflected, with the reflected ray having the same angle to the surface normal as the incident ray.

Properties of Light - 12.20.2017

Today we looked at five different properties of light and how they are used to create photographs. At first it was difficult to understand by only looking at diagrams online, but once we gave it a shot ourselves trying to create, block and reflect light off of things it became a lot clearer.

Above are some of the ideas my group came up with in class.

Photos 1 and 2 are diffuse reflection as the surface of the wall made the light scatter making the image unclear.

Photos 3, 4 and 5 are refraction of light created by placing a glass of water in front of different coloured paper or a landscape background which caused the image to be flipped in the reflection of the water.

The light wave could be absorbed by the object, in which case its energy is converted to heat. The lightwave could be reflected by the object. And the lightwave could be transmitted by the object. When this occurs, objects have a tendency to selectively absorb, reflect or transmit light certain frequencies.
