Intensity of sound is defined as the energy propagated through unit area. The energy here is nothing but the energy possessed by the particles of the medium as they get vibrated. So the energy is found to be due to each particle as 2 pi2 m a2 f2
Hence the intensity seems depending on:
1. mass of the particle ie medium
2. amplitude of vibration that too its square
3. square of the frequency of the vibration.

What are some of the factors that affect the rate of photosynthesis?
Temperature, concentration of CO2, and light intensity
What factors affect the speed of sound in a medium?
Temperature, coefficient of restitution, density are some of the factors that affect the speed of sound in a medium.
What factors affect the speed of wave?
Some factors that affect the speed of sound waves are density of medium, temperature, direction of wind, and humidity. Remember that a sound wave is just a pressure disturbance that travels through a medium by particle interactions. The nature of the medium will affect the sound waves velocity.
Which of the following does not affect photosynthesis rate of a plant?
intensity of lightIt is affected by temperature, pH , intensity of light . Other physical factors do not affect much
The amplitude of a sound wave determines its?
The loudness has to do with the sound field quantity called sound pressure or sound pressure level (SPL). The sound intensity or acoustic intensity means the sound energy quantity. Our ears and the microphone diaphragms are moved by the sound pressure variations.
What are some factors that affect photosynthesis?
The factor that will effect photosynthesis the most is light. Plants need light in order for photosynthesis to take place. Water, air, pH, and temperature will also effect photosynthesis.
What makes the speed of sound change?
There are some factors. Temperature, medium are that factors.
What factors affect the rate weathering?
Some factors that affect the rate of weathering are the type of rock, the altitude and the climate.
What factors affects salinity?
There are several factors that affect salinity. Some of the main factors include evaporation and precipitation which will affect the salinity of oceans and seas.
What factors affect sound waves?
The more dense a material is the faster sound will travel. Sound is dampened when the medium it is traveling through doesn't vibrate well; and when two different sounds cross there will be some places where the sound is amplified and where it is cancelled out, it has to do with the alignment of the crests and troughs, this is a phenomena that occurs with sound and light.
What are some biotic and abiotic factors that affect an ostrich?
trees affect it and its suroundings
What are some factors that affect your body weight?
I think that some factors that affect your body weight are: a) Depression b) Physical Activity c) Self esteem
