Question

the effect of glass prism is only to seperate seven colours of
a) White Light
b) Sunlight
c) Light of bulb
d) All​

Answer 1

Answer:

white light

Explanation:

The effect of glass prism is only to separate the seven colours of white light. A similar band of seven colours is produced when a beam of white light from an electric bulb falls on a triangular glass prism.

Answer 2

The effect of glass prism is only to separate seven colors of d) All.

Explanation:

• An optical prism is a transparent optical element with flat, polished surfaces that refract light.

• Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, acrylic and fluorite.

• Light consists of more than one frequency of electromagnetic wave.

• Sunlight consists of seven visible wavelengths. When it crosses through prism, it is dispersed and separated into all those seven colors.
• Spectrum of white light: The band of seven colors formed on a white screen, when a beam of white light is passed through a glass prism, is called spectrum of white light.
• White light is a mixture of seven colors of different wavelengths (colors) viz. violet, indigo, blue, green, yellow and red.
• Red color has the highest wavelength while the violet color has the lowest wavelength.
• As the ray of white light passes through a prism, the various constituents of the white light deviate through different angles and we see the incident ray splitting into 7 different rays on coming out of the prism.
• Prism only acts as a medium for the separation of the seven colors. When light falls on the glass prism, refraction takes place.
