3.00 x 108/ 1.49 = 2.0134 x 108 m/s
Therefore light will travel through acrylic at 2.01 x 108 m/s.
why did you observe with indices of refraction of the colors of light in the acrylic prism
We can probably look up the index of refraction for acrylic somewhere. But in order to answer the question, we'd still have to know what medium the light is coming out of when it hits the acrylic. All the action takes place at the interface, and we have to know the conditions on both sides.
Index Of Refraction
Fill a glass with water. Put a straight rod or pencil into the water at an angle. You see an apparent bend in the straight rad. This is caused by the different indexes of refraction of air and water.

The indices of refraction for different colors of light in an acrylic prism vary slightly, with red light having a slightly lower index compared to blue light. This results in the dispersion of light into its constituent colors when passing through the prism, creating a rainbow effect. The overall index of refraction for acrylic is around 1.49-1.50, causing the bending of light as it enters and exits the prism.
Light travels faster in water than in oil. The index of refraction for water is approximately 1.33, while for oil, it is around 1.45. A lower index of refraction indicates that light will travel faster through that medium, so since water has a lower index than oil, light travels faster in water.
It will travel with speed about 0.844 meter per second
Water's index of refraction is 1.333
The index of refraction is given by the ratio of the speed of light in a vacuum to the speed of light in the medium. Snell's Law states n1sin(theta1) = n2sin(theta2), where n1 and n2 are the indices of refraction and theta1 and theta2 are the angles of incidence and refraction, respectively. For light traveling from air (n=1) into acrylic (n_acrylic), the expression can be written as: 1sin(theta1) = n_acrylicsin(theta2), and the index of refraction for acrylic can be calculated by n_acrylic = sin(theta1) / sin(theta2).
The index of refraction affects the reflection properties of a mirror by determining how much light is reflected and how much is transmitted through the mirror. A higher index of refraction results in more light being reflected, while a lower index of refraction allows more light to pass through the mirror.
The low index of refraction in optical materials is significant because it determines how light waves travel through the material. A low index of refraction means that light waves will bend less when passing through the material, leading to less distortion and better optical clarity. This property is important for creating high-quality lenses and other optical devices.
Index Of Refraction
The index of refraction of a material is related to the speed of light in that material. Ruby has a lower index of refraction than diamond because light travels faster through the ruby compared to diamond. This difference is due to the different arrangement of atoms and the properties of the materials.
A material's index of refraction is related to its optical density through Snell's Law, which relates the angles of incidence and refraction as light passes through the interface between two materials with different refractive indices. A higher index of refraction usually corresponds to a higher optical density, meaning that light travels slower through the material.
