explain dispersion of sunlight through a glass prism with diagram?
Answers
Answer:
Dispersion of Light' can be defined as the splitting of white light when it passes through a glass prism into its constituent spectrum of colors (i.e. violet, indigo, blue, green, yellow, orange and red). ... The white light splits into its constituent colors at various frequencies and various angles.
• The glass prism is a transparent object with two triangular ends and three rectangular sides.
• Refraction of sunlight in a glass prism is different from a glass slab.
• Because the incident ray of light in a glass prism is not parallel to the incident ray of sunlight.
• When a ray of sunlight enters the glass prism, it turns twice.
• First when it enters the glass prism and second when it comes out of the prism.
• This is because the refracted surfaces of the prisms are not parallel to each other. In addition, the beam of light bends towards its base as it passes through the prism.
Explanation
• In 1665, Isaac Newton discovered that there are seven colors in white light. He discovered that if a ray of white light passes through a glass prism, it splits into seven colors. These colors are : Red, Orange, Yellow, Green, Blue, Indigo and Purple form - "VIBGYOR".
