Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Remember those old monster movies‚ the kind with giant creatures chasing after people‚ destroying objects wherever they go? Some of them can fit in the palm of your hand with ease. Forced perspective photography is used make us‚ the viewers believe that certain objects are smaller or larger than they really are. It’s the manipulation of the human visual perception; some call it optical illusions. Taking a forced perspective photo is not difficult and doesn’t require any special skills. All you need

stimulus‚ and share information between the cerebral hemispheres. Procedure Participants were positioned in-front of the visual field and instructed to speak the word displayed and retrieve the object. When testing the phenomenon‚ the brain and optic chiasm was split. Therefore‚ the patient was only able to transfer visual information from the left eye to the left brain‚ promoting the function of the corresponding hand and vice versa. References Gazzaniga‚ M.

Reflection (physics) From Wikipedia‚ the free encyclopedia The reflection of Mount Hood in Mirror Lake. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light‚ sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected

focused into the retina containing receptor cells called rods and cones. Rods assist vision in low-level light‚ whilst cones‚ located primarily in the fovea are responsible for detecting fine detail and colours. The rods and cones are linked to the optic nerve‚ which send information via the lateral geniculate to the visual cortex. The visual cortex is responsible for processing the incoming visual information (Pike & Edgar‚ 2010 pp 66 & 94); how this information is then interpreted is what we term

Nell has never been taught of any kind of conventional language. Her childhood was completely isolated from the outside world. As the result‚ the only person she could communicate with was her little twin sister. And what they used to communicate with each other was their own made-up language. After her twin sister’s death‚ her imagination about her twin sister has

Light Effects Refraction‚ reflection and dispersion are all processes which happen when a ray of light is shone at either a glass block‚ a mirror or a prism. The ray box is the light source. Mirror When the ray box is shone at a mirror the angle of incidence is always a few degrees different to the angle of reflection. For example‚ if you shine a light ray into a mirror at 60* then it will reflect out at about 57*. Glass Block If I shine a light ray into a glass block then the light would

Some terms related with reflection are – 1. Incident Ray - The light ray striking a reflecting surface is called the incident ray. 2. Reflected Ray – The light ray obtained after reflection from the surface in the same medium
