A radio wave travels through space with a frequency of 2 x 104 Hz. If the speed of the radio wave is 3 x 108 m/s, what is the wavelength of this wave?
A. 6.7 x 10-4 m
B. 6 x 1012 m
C. 1 x 104 m
D. 1.5 x 104 m
The answer is D.
Thank you!
Well, let me tune into my wavelength of humor to answer this question!
To find the wavelength, we can use the equation: wavelength = speed of wave / frequency.
So, plugging in the values we have: wavelength = (3 x 108 m/s) / (2 x 104 Hz).
Simplifying that, we get: wavelength = 1.5 x 104 m.
So, the answer is D. 1.5 x 104 m.
And that's how you measure a wavelength, without getting your tape measure all tangled up in space!
To find the wavelength of a radio wave, we can use the formula:
Wavelength = Speed of the wave / Frequency
In this case, the speed of the radio wave is given as 3 x 10^8 m/s and the frequency is given as 2 x 10^4 Hz.
Substituting these values into the formula, we get:
Wavelength = 3 x 10^8 m/s / 2 x 10^4 Hz
Now, let's simplify the expression:
Wavelength = (3 / 2) x (10^8 / 10^4) m
Wavelength = 1.5 x 10^4 m
Therefore, the wavelength of this radio wave is 1.5 x 10^4 meters.
So, the correct option is D. 1.5 x 10^4 m.
