ANSWER:
The answer will be OT
Answer B is the correct pair.
Answer:
The waves will increase in frequency
Explanation:
As the young girl moves her hand back and forth faster, it will be observed that number of back and forth motions increase every second. Also the distance between crest and trough of the wave (wavelength) will be reduced as she moves her hand back and forth faster.
Frequency = number of turns (moves) per second
The waves will increase in frequency since there will be more number of back and forth motions in every second.
Also,
The distance between crest and trough will be reduced, which implies that there will be decrease in waves wavelength.
This can also be verified using wave equation;
V = Fλ
At constant velocity,
F ∝ ¹/λ
Thus, decrease in wavelength will cause increase in frequency of the waves.
The right answer is : The waves will increase in frequency
Answer:
One newton is a unit of force equal to the force needed to move a one kilogram mass by one meter per second per second. Word originsThis word is named for Sir Isaac Newton (1642-1727), the great English mathematician and physicist who discovered gravity.
