Consider a Young's two-slit experiment in which the wavelength of light is 35% smaller than the distance between the slits.
A. How many complete dark fringes would be seen on a distant screen? (Assume for all these questions that the screen is as large as it needs to be.)
B. How many total interference maxima would be seen on a distant screen?
C. Now suppose that the wavelength of light is 125% larger than the slit separation. How many complete dark fringes would be seen on a distant screen?
In determining the specific heat of a new metal alloy, 150g ofthe substance is heated to 400C and then placed in a 200g aluminium calorimeter containing 400g of water at 10C. If the final temperature of the mixture is 30.5C, what is the specific h..
