The radio station WBRU broadcasts in the radio spectrum at 95.5 MHz. What is the wavelength of this electromagnetic wave in meters?
frequency*wavelength=speedofLight
solve for wavaelength
divide the speed of light (3.0 x 10 to the eighth power) by the frequency
To find the wavelength of an electromagnetic wave, you can make use of the equation:
wavelength = speed of light / frequency
The speed of light is a constant value, approximately 3 x 10^8 meters per second.
The frequency of WBRU is given as 95.5 MHz, which stands for 95.5 megahertz. To convert this value to hertz, we need to multiply it by 10^6 since 1 MHz equals 10^6 Hz.
Let's plug the values into the equation to calculate the wavelength:
wavelength = (3 x 10^8 m/s) / (95.5 x 10^6 Hz)
The Hz unit cancels out, leaving us with:
wavelength = (3 x 10^8 m) / (95.5 x 10^6)
Now, simplifying the equation:
wavelength ≈ 3.14 meters
Therefore, the wavelength of the electromagnetic wave broadcasted by WBRU is approximately 3.14 meters.
