Nature av SPH 4U In the space below, clearly and neatly sketch a graph of light intensity versus position on the screen 3) a single slit interference pattern. Label its features, including their sizes on the screen. (12) miniuna? inconsistent labels? Secondary may . spacks talvary mul, 4) Water waves with a wavelength of 3.1 cm travel with a speed of 22 cm/s. They pass into a region where their speed increases to 36 cm/s. What are the wavelength and frequency of the waves in this region? (12) 5) Ethanol has an index of refraction of 1.43. Light travelling through ethanol is incident on a boundary with water (index 1.33) with an angle of incidence of 18. What is the angle of refraction? (12) 6) A point on the 3" nodal line of a two point interference pattern is 14.0 cm from one of the sources. The wavelength is 3.1 cm. What distance is this point from the other source? (14) 7) A point on the fourth nodal line of a two point interference pattern is 11.7 cm from the perpendicular bisector of the sources, and 47.0 cm from the midpoint of the sources. The sources are 6.5 cm apart. What is the wavelength? (10) B) Light of wavelength 538 nm is incident on a single slit of width 0.11 mm. What is width of the central maximum of the interference pattern produced on the screen 5.8 m away? (12) 9) Light falls on two slits with a separation of 0.12 mm. On the screen 4.1 m away, there is a distance of of the light? (12) 5.7 cm from the centre of the pattern to the 5" order bright fringe on either side. What is the wavelength 10) Light with a wavelength of 605 nm is incident on a double slit, where each slit is 0.12 mm wide, and the slits are 0.75 mm apart. What is the angle from the centre of the interference pattern to the secondary fringe?
