Sunlight reaches to us in composite from and not in it’s constituent colours because vacuum is non- dispersive . speed of all colours is same in vacuum. light behaves like a particle in vacuum. light travels in a straight line in vacuum

A: Ray optics assumes that light travels in a straight line which is disapproved by diffraction effects, yet the ray optics assumption is so commonly used in understanding location and several other properties of images in optical instruments. R: Typical sizes of apertures involved in ordinary optical instruments are much larger than the wavelength of light.

Light after being a wave motion, appears to travel in straight line because
