A microwave oven operates at 2.40 GHz. What is the wavelength of the radiation produced by this appliance?
I got 1.25*10^-10.
What am I doing wrong?
Is the speed of light 3 x 10^8 m/s?
Is 2.5 GHz 2.5 x 10^9 Hz?
Does 0.125 m wavelength sound better?
oh my! thank you, conversion factors off i guess :[
To find the wavelength of the radiation produced by a microwave oven, you can use the formula:
Wavelength = Speed of Light / Frequency
Where the speed of light is approximately 3.00 x 10^8 meters per second (m/s) and the frequency is given in hertz (Hz).
In this case, the frequency is 2.40 gigahertz (GHz), which is equivalent to 2.40 x 10^9 Hz.
Therefore, substituting the values into the formula:
Wavelength = (3.00 x 10^8 m/s) / (2.40 x 10^9 Hz)
Calculating this expression gives:
Wavelength = 1.25 x 10^-1 meters or 0.125 meters
So, the correct wavelength of the radiation produced by the microwave oven is 0.125 meters or 1.25 x 10^-1 meters.
It seems like you made an error in your calculation. You may have accidentally multiplied instead of dividing in the formula.
