Ray Optics Questions

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.
