Question

Calculate the wave length and wave number of a radiation having frequency 1.4×10^14 Hz​

Answer 1

Answer:

Frequency is expressed in Hz (Frequency = cycles/seconds). To calculate the time interval of a known frequency, simply divide 1 by the frequency (e.g. a frequency of 100 Hz has a time interval of 1/(100 Hz) = 0.01 seconds; 500 Hz = 1/(500Hz) = 0.002 seconds, etc.)

Frequency and period are inversely related quantities. ... Frequency is the number of cycles/second denoted as Hertz (Hz). Period is the seconds/cycle. Inverse because if the frequency is high, then the time period is low.

Sound waves, unlike quantum waves, don't have frequency proportional to energy. The frequency of sound doesn't decrease with distance, but it does derease with increasing distance, meaing it does go through the doppler shift, same as light.
