Sunlight is available as a source of energy . The sunlight is very much important in
In the formation of primary rainbow, the sunlight rays emerge at minimum deviation from rain-drop after
In the formation of primary rainbow, the sunlight rays emerge at minimum deviation from rain- drop after
Assertion : The rainbow is an example of the dispersion of sunlight by the water drops in the atmosphere. Reason : No reflection or refraction of light is involved in the formation of rainbow.
Rainbow occurs due to refraction, dispersion, "….............." and again refraction of sunlight by water droplets.
A man is Standing on the peak of a mountain and finds that evening sun rays are nearly horizontal. At a horizontal distance of 6 km from him, its raining and he sees a beautiful rainbow. The sun rays entering water drop get refracted, reflected and refracted to form a rainbow. The red light is emitted from a drop upto a maximum angle of 42° with respect to the incident sunlight. In front of the man there is a flat valley at a depth of 0.5 km from the mountain peak. What fraction of the complete circular arc of the rainbow is visible to the man?
