Chapter 10 -Wave Optics Very Short Answer Questions 1 Mark 1. Draw a diagram to show cylindrical wave front. Ans: 2. A light wave enters from air to glass. How will the following be affected? a) Energy of the wave Ans: When light wave enters from air to glass, part of light is reflected back into the air.
the two waves become more in phase and the sound gets louder again . 1 . 1 . 1 . 1 . Alternative: Constructive interference occurs when the path difference is a whole number of wavelengths and the waves are in phase. Destructive interference occurs when the path difference is an odd number of half wavelengths and the waves are in antiphase.
The document covers topics in wave optics, including derivations of laws of reflection and refraction using Huygens' principle, interference patterns in Young's double slit experiment, diffraction patterns from slits, and the concept of polarization. It includes a series of questions and answers related to these concepts, exploring effects of various conditions on interference fringes ...
Solution: We know that the speed of the wave is equal to the product of the frequency and the wavelength. The frequency of the water wave is 5 Hz (since the cycle is 5 times per second) while its wavelength is 3 m, so the speed of the water wave is 15 m/s. Problem 2: As the ambulance goes near you, does the speed of the sound wave increase or
