What is the frequency of waves heard by the insect

Reference no: EM13656540

A resting bat sends out ultrasonic waves at 50 kHz towards an insect that is approaching the bat with a speed of 20.0 m/s.

1) What is the frequency of waves heard by the insect?

2) Compute the frequency of the return waves after reflection from the insect (the insect becomes the source) and reaching back to the bat
