Question

If the distance between the highest and lowest point of a transverse wave is 17 cm, calculate the amplitude of the wave.

• A. 8.05 cm
• B. 8.5 cm
• C. 0.85 cm
• D. 85 cm

Answer 1

The correct option is B

8.5 cm

Since, the amplitude of the wave is measured from the mean position, it will be exactly half of the distance between the highest point of a crest and trough. So we have, amplitude as A = half of the distance between the highest point of a crest and trough

i.e. A = $\frac{17}{2}$

So, A = 8.5 cm (Answer)
