Question
Figure below shows the distance-displacement graph of two waves A and B. Compare
- the amplitude,
- the wavelength of the two waves.
Solution
Amplitude is the maximum displacement from the mean position.
For A maximum displacement = 10 cm and
for B the maximum displacement = 5 cm.
(i) The ratio of maximum amplitude is `"A"_1/"A"_2 = 10/5 = 2 : 1`
Wavelength of A = 8 cm
Wavelength of B = 16 cm
(ii) The ratio of wavelength is `lambda_1/lambda_2 = 8/16 = 1 : 2`
