Can you ever have a situation in which a light ray goes undeviated through a prism ?

For refractin of light through a prism

Which light has minimum speed in glass (prism)?

Figure shows the graph of angle of deviation del versus angle of incidence i for a light ray striking a prism. The prism angle is

State the causes of dispersion of white light as it passes through a triangular glass prism.

The base of an equilateral triangle ABC is BC. When it is arranged in four different situations and white light is incident on it, then in which of the following arrangements of the prism, the third colour from the top is the colour of clear sky in dispersion of light is produced ?

Give the relationship between wavelength of light and its angle of deviation, when it is passed through a prism.

The angle of incidence for a ray of light at a refracting surface of a prism is 45^@ . The angle of prism is 60^@ . If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are
