B.
increases as the tension of the string increases
The energy of a photon of light is directly proportional to its frequency and <span>inversely</span> proportional to its wavelength.
Answer:
3. The driving frequency is not matched to the natural frequency of the oscillatory system.
Explanation:
- It is the condition of resonance when the one body that oscillates with a maximum amplitude when the frequency of the applied force is equal to the natural frequency of the body.
- Every body has its own natural frequency.
- Here the driving force may be more or less but we are sure that it is not equal to the natural frequency of oscillatory system. Hence the force is not in resonance with the oscillatory system.
The sound gets louder as it gets closer and when it passes is gets softer
