wave theory of light

Wave theory of light explains that light behaves like a wave, similar to ripples on a pond or sound waves, with properties such as wavelength, frequency, and amplitude. This means light can bend around objects (diffraction), overlap (interference), and spread out after passing through small openings. Light waves are oscillations of electromagnetic fields that travel through space at a constant speed, enabling phenomena like colors, spectrum, and the way light interacts with materials. The wave theory helps us understand many behaviors of light beyond simple straight-line travel, highlighting its wave-like nature in various optical phenomena.
