Answer explanation

Radio station WKLB in Boston broadcasts a frequency of 99.5x10^6 MHz. What is the wavelength of the radio waves emitted by WKLB? (Speed=3.00x 10^8 m/s) SHOW YOUR WORK (as best as possible)

Evaluate responses using AI:

OFF

Answer explanation

Speed=wavelength times frequency. Wavelength=3.00x10^8 m/s times 99.5x10^6 MHz.

Wavelength is 3.02 m

One end of the rope is vibrated to produce a wave with a wavelength of .25 m.  The Frequency of the wave is 3.0 Hz.  What is the speed of the wave? SHOW YOUR WORK (as best as possible):

Evaluate responses using AI:

OFF

Answer explanation

Speed=wavelength times frequency.

.25m times 3.0Hz

Speed =.75 m/s
