radiation?
Microwave ovens emit microwave energy with a wavelength of 12.8 cm. What is the energy of exactly one photon of this microwave radiation?
1. Microwave ovens emit microwave energy with a wavelength of 12.5 cm. What is the energy of exactly one photon of this microwave radiation? 2. A certain shade of blue has a frequency of 7.18x10^14 Hz. What is the energy of exactly one photon of this light?
5. Microwave ovens emit microwave radiation that is absorbed by water. The absorbed radiation is converted to heat, which cooks the food. One particular oven emits microwaves with a wavelength of 10.8 cm. How many microwave photons are required to heat 150.0 mL of coffee from 20.0°C to 70.0°C? (q = mcpAT; Cwater = 4.18 J/gºC)
6. A) Microwave ovens use microwaves at a frequency of 2450MHz. What is the wavelength of this electromagnetic radiation? B) What is the energy of a photon at that frequency?
Compare green and yellow light from the visible spectrum. Which has the longer wavelength? Which has the greater frequency? Which has the greater energy?Microwave ovens emit microwave energy with a wavelength of 12.3 cm. What is the energy of exactly one photon of this microwave radiation?
Microwave radiation has a wavelength of 1.0 cm. Calculate the energy of a single photon of this radiation andf then calculate the energy of 1.0 mol of the radiation.
Microwave ovens use microwave radiation to heat food. The microwaves are absorbed by moisture in the food, which is transferred to other components of the food. As the water becomes hotter, so does the food. Suppose that the microwave radiation has a wavelength of 11.2 cm. How many photons are required to heat 200 mL of coffee from 25 C to 63 C?
Microwave ovens heat food by creating microwave electromagnetic radiation that is absorbed by water molecules in the food. Any material that does not have water in it will not absorb the radiation and will not get hot. Metals reflect the microwaves from their surfaces and disrupt the operation of the oven. Some Australians heat water in microwave ovens to make tea. What is the minimum number of microwave photons with a wavelength of 3.17 mm that will have to be...
What is the energy in joules of one photon of microwave radiation with a wavelength of 0.122 m? A. 2.70x 10-43 J B. 5.43x 10-33 J C. 1.63 x 10-24 J D. 4.07 x 10-10 J E. 2.46 x 109 J
Using Microwave Radiation to Heat Coffee (expanded) Microwave ovens use microwave radiation to heat food. The microwaves are absorbed by the water molecules in the food, which is transferred to other components of the food. As the water becomes hotter, so does the food. Part A Suppose that the microwave radiation has a wavelength of 12.4 cm . How many photons are required to heat 215 mL of coffee from 25.0 ∘C to 64.6 ∘C? The coffee has a density...
