Chapter 9: Ray Optics and Optical Instruments - Assertion-Reason Quiz

Assertion (A): Light travels in a straight line (ray approximation) when interacting with objects much larger than its wavelength. Reason (R): When the wavelength of light (~500 nm) is much smaller than the size of objects encountered, diffraction effects are negligible and the ray model is valid.
