Microwaves are electromagnetic waves transmitted at a normal frequency of 2.45 GHz. Find the wavelength of the microwaves.
λ =c/f = 3•10^8/2.45•10^9 =0.122 m
To find the wavelength of microwaves, we can use the formula:
Wavelength = Speed of Light / Frequency
The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second (m/s), which is a constant value.
The given frequency of microwaves is 2.45 GHz. To use this value in the formula, we need to convert it to Hz by multiplying it by 10^9.
So, the frequency in Hz is 2.45 GHz x 10^9 = 2.45 x 10^9 Hz.
Now we can substitute the values into the formula:
Wavelength = 3.00 x 10^8 m/s / 2.45 x 10^9 Hz
Calculating this gives us:
Wavelength = 0.1224 meters
Therefore, the wavelength of the microwaves is 0.1224 meters.
