6. A simple pendulum with mass (m) of 1,00 kg and length (L) of 1,00 m has a maximum horizontal displacement of 3.00 cm from its equilibrium position. If the energy of this pendulum is quantized, 03 what is the quantum number (n) of the pendulum? (g=9.8 ms) Page 1 of 1 PHY 1051 3. maginea 4. 03 system in which inter slit separation is twice the slit width. How many 03 interference fringes lie in the central diffraction envelope? Draw a suitable plot. An antireflective coating having refractive index 1.29 is applied on a glass plate having refractive index 1.49. Draw the light path through the film and with proper explanation, calculate the least thickness of coating to be applied so as to minimize reflection of 560 nm light? In a single-slit diffraction pattern, assuming each side maximum is halfway between the adjacent minima, find the ratio of the intensity of (a) the first-order side maximum and (b) the second-order 03 side maximum with respect to the intensity of the central maximum 5. 04 1. What are Newton rings? Why they are circular? With a neat geometry, obtain an expression for the radil of dark rings 2 If a particle with mass m, is travelling with relativistic speed, show that me foc + 04 -4G Where, and fare de-Broglie wavelength and frequency of the particle
