Canvas HW09; Due before class on Wed. 4/20.
A small microwave oven is shown below, looking at it from overhead. (The circle in the middle
of the 30cm x 50cm oven is where you put your food.) The mechanism that turns the circle is
broken; the food does not rotate.
The microwaves come from a common source, through two tubes, as shown. The two tubes
have the same length. They enter the oven from both sides, 5cm from the back of the ovén.
Redraw the main oven (30cm x 50xm) as a rectangle on your solution.

A) If the microwaves have a frequency of 1.5 GHz, what is their wavelength?
B) Locate one place in the oven where you would expect destructive interference that would
leave a cold spot in your food. (Ignore reflection off the walls.) There are many possible
solutions, but try to find a simple one where you can precisely calculate the location of the cold
spot.
When the light is passing from rarer to a denser
medium, which is the correct statement?
O a. angle of incidence is greater than angle of
refraction
O b. angle of incidence is equal to angle of
refraction
O c. angle of incidence is less than angle of
refraction
O d. angle of incidence is equal to critical angle
In the figure below, light is traveling in mediums with
indexes of refraction, n, and n,. Is n¡ less than n2, n¡ greater
than
n,, or n, equal to n,? Why? If n, = 1.33, find n,
