Question

What is the minimum distance between two crests called?

• A. Wavelength
• B. Amplitude
• C. Displacement
• D. Wave pulse

Answer 1

The correct option is A Wavelength

The minimum distance between two consecutive crests is called the wavelength of the wave.

Note$:-$ In question it is not written that crests are consecutive, but it is necessary condition to be wavelength that crests should be consecutive, else it can't be the wavelength.

$\therefore$ Option (a) is the correct answer.
