After tracing the path of a ray of light through a glass prism a student marked the angle of incidence (∠i), angle of refraction (∠r) angle of emergence (∠e) and the angle of deviation (∠D) as shown in the diagram. The correctly marked angles are :
(A) ∠i and ∠r
(B) ∠i and ∠e
(C) ∠i, ∠e and ∠D
(D) ∠i, ∠r and ∠e
Fill in the blank with suitable word:
When a ray of light enters a prism, it bends ................ the normal ; as it leaves the prism, it bends ................. the normal.
The splitting up of white light into seven colours on passing through a glass prism is called:
(a) refraction
(b) deflection
(c) dispersion
(d) scattering
Why do you not see a spectrum of colours when light passes through a flat pane of glass?
What do you understand by the term spectrum? Name the various colours present in the spectrum of sunlight.
When we place a glass prism in the path of a narrow beam of white light a spectrum is obtained. What happens when a second identical prism is placed in an inverted position with respect to the first prism? Draw a labelled ray diagram to illustrate it.
Draw a labelled diagram: Dispersion of light through a prism.
Differentiate between a glass slab and a glass prism.
Observe the given figure and answer the following questions.
- Which colour light rays bend most?
- Which colour light rays bend least.
- What is the wavelength of violet light rays?
