1.

Explain with figure(graph):wave length and periodic time​

Answer»

Answer:

Definition: Wavelength can be defined as the distance between two successive crests or TROUGHS of a WAVE. Wavelength is the distance from one crest to ANOTHER, or from one trough to another, of a wave (which may be an electromagnetic wave, a sound wave, or any other wave).

The period of a wave is the time for a particle on a medium to make one complete VIBRATIONAL cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years. The period of orbit for the Earth AROUND the Sun is approximately 365 days; it takes 365 days for the Earth to complete a cycle.
