Which sets of data show a wave with the shortest wavelength?
A. Speed=100 million m/s and frequency = 50 million Hz
B. Speed=150 million m/s and frequency=1500 Hz
C.Speed=300 million m/s and frequency= 100 Hz

B. Speed=150 million m/s and frequency=1500 Hz
C.Speed=300 million m/s and frequency= 100 Hz

Frequency times wavelength will give you the speed of the wave, can you solve it now?

B?

snowfire · Answer

Be careful with units, 1500 Hz is not on the same power as 150 million. You would need a wavelength of 100000 m for that to be the case, which is not the lowest of these choices.

anonymous · Answer

So it'd be C will the lowest walength and A with the highest wavelength

snowfire · Answer

Do the math; what wavelength do you need for A and what do you need for C?
