1.Wavelength(λ)= _____________ cm(Remember what you measured isλ/2. Hint: This is a whole number.) [5 pts]Note that since the speed of light is usually given in meters per second, all of our measurements have to be in meters.2.Wavelength (λ) = ____________________ m (Convert cm to m.) [Use scientific notation here. Round to1decimal.] [5 pts]3.Frequency () = _____________________ Hz (Hz is the number of wavelengths passing a point in 1 second.) [10 pts]The frequency is 2450 MHz. You need to translate this to scientific notation. (Hint: Convert MHz to Hz.) [Round to2decimals.]4.Velocity (v) = _______________________ m/s [Use scientific notation here. Round to2decimals.] [10 pts]This is the speed of the microwaves, which as electromagnetic radiation move at the speed of light.The official speed of light is given as 2.99792458×108m/s. What percent of the actual speed is your “marshmallow calculated”speed?5.vmarshmallow/ 2.99792458×108×100 = _______________________% [Round to1decimal.] [10 pts]How does the door on a microwave oven allow us to see inside while keeping microwave radiation contained? [30 pts]The solid walls of the microwave oven keep the microwave radiation from escaping the oven’s interior.But the door to these ovenshas a glass window that we can see through. If you look closely at the door, you will see a metal grid sandwiched between the glasspanes of the window. How and why does the metal grid in the door of a microwave oven protect us from the microwave radiationreleased inside of the oven that cooks our food? To answer this question, you need to compare the wavelength of the microwaveradiation and the wavelength of visible light. Use the wavelength for the microwave radiation you calculated above. For visiblelight, use 500 nanometers. The openings in the metal grid found in microwave oven doors are about 1 mm in diameter. Note thatthese sizes need to be converted to a standard length—meters.6.Size of grid opening: 1 mm = ____________ m (Write this number using correct scientific notation.) [5 pts]7.λmicrowave= ____________________ m [Previously calculated in meters; use scientific notation. Round to1
