  • S.t : the characteristic by which the ear diffrentiate between  strong or weak sounds
    Sound intensity
  •  10
  • What is meant by sound pitch
    It is the property which the ears can differentiate between harsh and sharp voices
  •  20
  • G.R : the intensity of sound increase when the sound source toches a resonance box
    Due to the increase in vibrating surface area

  • What is meant by : speed light
    It is the distance covered by light in one sec.
  •  15
  • G.R : the energy of red light photon is less than that of orange light photon
    Because the frequency of red light photon is less than that of orange light photon
