Quiz_02 Interference pattern and intensity

Q1.1 The interference pattern for waves emitted by two coherent sources of equal strength is shown. Which is the correct statement that describes the situation at location C? This is a dark spot and the path difference from S1 and S2 =0.5*wavelength This is a bright spot and the path difference from S1 and S2 =2*wavelength This is a dark spot and the path difference from S1 and S2 =2.5*wavelength C

Q1.2 Consider the interference pattern from two identical radio antennae as shown. Based on this pattern, determine the wavelength of the radio wave. 400 m 300 m 200 m 100 m 50 m A sin theta = m/2 lambda/d for a minimum 2 sin(30)=lambda/400m lambda =400 m

The path difference and the wavelength of light. Q1.3 For 2-slits interference of light, the electric field at any point along the screen is given by the sum of two electric fields, one generated by slit 1 and one generated by slit 2. The path difference and the wavelength of light. The path difference only. The wavelength only. It does not depend on path difference nor the wavelength. A
