Which of the following coloured light has the least speed in glass prism?(a) violet (b) yellow (c) red (d) green
The colour of white light which suffers the maximum bending (or maximum refraction) on passing through a glass prism is:(a) yellow (b) orange (c) red (d) violet
Which of the two is scattered more easily : light of shorter wavelengths or light of longer wavelengths?
According to the visible spectrum wavelength (ROYGBIV), violet is at the bottom of the list which shows it is the shortest wavelength among all, so it should be the most refracted (scattered) light wave. Then, why do the sky, and the bottom colour of the rainbow appear blue, instead of violet?
A beam of white light falls on a glass prism. The colour of light which undergoes the least bending on passing through the glass prism is:(a) violet (b) red (c) green (d) blue
Which of the following colour of white light is least deviated by the prism?(a) green (b) violet (c) indigo (d) yellow
Which of the following salt has a blue colour and why?CuSO4.5H2O or CuSO4.
A student covered a torch with red cellophane sheet to obtain red light. Using the red light she obtains a shadow of an opaque object. She repeats this activity with green and blue light. Will the colour of the light affect the shadow? Explain.
Boojho has observed some plants with deep red, violet or brown leaves. He wants to know whether these leaves also carry out photosynthesis.
The red colour of the sun at the time of sunrise and sunset is because:(a) red colour is least scattered (b) blue colour is least scattered(c) red colour is most scattered (d) blue colour is most scattered
