7' in: this assessment, demonstrate your understanding of the wave nature of light by completing a "problem set , "Instructions " 5 Yourtask is to complete the questions in the problem set. Read each question carefully, identifying ' ' yourgiven values. Show all formulas, caloulations, and PR/PD analysis used to solve the problems. , "Report your answers to the correct number of significant digits and with the correct units. 7 Questions LA student meaSures the separation between the nodal lines on a double 'slit interference pattern using a red light of wavelength-650 11m to be it] m. it the incoming light is then changed to blue light of wavelength 745071331, calculate theseparation between the nodal lines. . 2. lithe angle, between the dark fringesinodal lines) on either side of the central maximum is 15 ' and the wavelength of the light is Elm am, what is the width of the single slit? :3. in a ripple tank with two point sources, the distance from a point on the second nodal line is 7 12 cm to one source and 8.\" 5 cm to the other: Calculate the wavelength of the source waves. 4. Thin coatings are sometimes applied on sunglasses to cause light that is reflected from them to have a particular true. What minimum thickness should be applied to sunglasses of n. z 1, 5 to maximize the reflection of red: light (650 mm)? The coating has a value of n 2 l. 4
