Question

Which wave has the greatest amplitude?

Answer 1

It is the red line the purple line carries the most the green line is the largest and the smallest is sky blue

Answer 2

Explanation:

The maximum displacement of the particles of wave is called its amplitude. The amplitude of purple wave is greatest i.e. wave A

The energy of wave is directly proportional to the square of amplitude. So, the purple wave carries the most energy i.e. wave A.

The number of oscillations or vibrations per unit time is called frequency of wave. The frequency of blue wave is largest i.e. wave C

The distance between two consecutive crests or two troughs is called the wavelength of wave. Wavelength and frequency have inverse relationship. So, the wavelength of blue wave is smallest i.e wave C
