In a two-slit interference experiment, a viewing screen is placed 5 meters directly behind two slits separated by 4 µm. coherent, monochromatic light of wavelength λ = 700 nm emerges (in phase) from the slits. (assume the slit width is very small compared to the wavelength λ.) 24. at what value of x on the screen does the largest-order intensity maximum occur (i. e., the one that is the farthest from the center line)? a. x = 1.2 mb. x = 4.4 mc. x = 5.0 md. x = 9.0 me. x = 15.7 mwhat happens to the separation between the existing intensity maxima on the screen as we increase the slit spacing? a. the separation decreases. b. the separation increases. c. there is no change.

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
