Physics - ICS Part 1 Physics Chapter 7 Short Questions Test

Question # 1

Briefly give two phenomena in which resonance plays an important role.

  • Ans 1: 1) Tuning a radio, we turn the knob to make the natural frequency of the electric circuit of receiver equal to the transmission frequency of the radio station. When the two frequencies match, energy absorption is maximum and this is the only station we hear.
    2)Food can be easily cooked in a microwave oven. The waves produced in this type of oven have a frequency of 2450 Mhz. At this frequency the waves are absorbed due to resonance by water and fat molecules in the food.

Question # 1

How the phenomenon of resonance is produced?

  • Ans 1: When the frequency of the applied force is equal to the natural frequency of simple harmonic oscillator, the periodic amplitude of the motion may become extraordinary large. This phenomenon is called resonance.
