Q. Why, And
white reflects all wavelengths of light?

Statement 1: When a white light ray passes through a prism it disperses into seven different colours, and this phenomenon is called dispersion.

Statement 2: Refraction depends upon the wavelength of light and since different colours have different wavelengths, they are refracted at a different angle.
