a) A light diffraction occurs when waves impinge on an obstacle and the waves bend behind it. Consider two spotlights located near to each other. Will there be any interference occurred? Justify your answer. (4 marks) b) Consider a double slit experiment as illustrated in Figure 4. There are several bright fringes can be seen on a screen with 7.0 m away and the wavelength of the light is 200 nm. i. What is the separation distance, d between the two slits, if the value of xz is 9.0 mm? ii. Calculate the wavelength of the light if the distance between the second order and third order of the interference fringes is 3.0 mm. Show your working steps. He ਤੇਰੀ । Bright Interference fringe's view 7 m Figure 4 (12 marks) c) 2 Describe a blackbody radiation and how does it relate to Wien's law. Consider a star has a yellow colour with a wavelength of 460 nm. Calculate the possible surface temperature of the star. (4 marks)
