Question

An ultraviolet radiation has a wavelength of 300Å. If the velocity of electromagnetic wave is
3 x 108 ms 1. Calculate (i) frequency
(ii) time period.
[(i) 1016 Hz (ii) 10-16 ]
2. The wavelength of the vibrations produced on the surface of water is 2 cm. If the wave velocity is 3× 10⁸ms-¹ calculate
(i)frequency
(ii)time period ​

Answer 1

Answer:

There are many types of waves, such as water waves and even earthquakes. Among the many shared attributes of waves are propagation speed, frequency, and wavelength. These are always related by the expression vW=fλ. This module concentrates on EM waves, but other modules contain examples of all of these characteristics for sound waves and submicroscopic particles............................/.....................
