10. If VB, VG, VR be the velocity of blue, green
and red light respectively in a glass prism,
then which of the following statement gives
the correct relation?
a) V3 = Vo = VR b) V8 > VG>VR
c) VB<VG<VR d) VB<VG> VR
Answers
Answer:
C
Explanation:
In the separation of white light into it's component colours, the order of dispersion is from red to violet (ROYGBIV) in an increasing order meaning red deviated least. The short deviation of red light is because it possesses the smallest wavelength and thus the highest speed or velocity. The speed or velocity reduces as the deviation increases. Therefore, green light possesses more speed(velocity) than blue light while red light has the highest of them all.
Answer:
C
Explanation:
light is in the form of waves, It is characterized by a wavelength (A) and a frequency (V),Which
are related by the following equations: C = VA
( C- Velocity of light).
1. light is a form of energy which travels along a straight line,
2. lens formula
1/f = 1/v - 1/u
