Which physical quantity remain unchanged when light and sound passes through medium?
Its FREQUENCY remains the same. Remember that when sound waves travel from air to water, its frequency remains the same, which is why people do not seem to have higher or lower voices under water. However the amplitude and velocity do change if it is a sound wave.
The pitch of a sound wave is its wavelength?
Kind of. The pitch of a sound wave is its frequency, and because frequency = 1 / wavelength its pitch is related to the wave length. So to answer, no, the pitch of sound is not the wavelength itself, rather it is the inverse of the wavelength ( 1/wavelength)falseACJM
What is the relationship between wavelength of light and the quantity of energy per photon?
The energy per photon is directly proportional to the frequency; the frequency is inversely proportional to the wavelength (since frequency x wavelength = speed of light, which is constant); thus, the energy per photon is inversely proportional to the wavelength.
How are wave speed frequency and wave length related to the wave amplitude?
Frequency is the amount of bumps there are in the wave. The higher the frequency the lower the wave length and vise versa. some equations are E=hv C=vw h=Plancks Constant(6.626x10 to the -34) C=3.0x10 to the power of 8
How does the various kinds of EM waves differ from each other?
They differ in frequency. (That's exactly the same thing as saying that they differ in wavelength, since frequency and wavelength are firmly connected.) (That's also the same thing as saying that they differ in the quantity of energy carried by each photon, since the amount of energy carried by each photon is firmly connected to frequency.)
Is light digital or analog quantity?
Yes, insofar as any quantity can be truly analog on a macroscopic scale. Disregarding the quantized nature of light at quantum dimensions, the frequency, wavelength, and amplitude of light aren't restricted to any set of definite values. Between any two levels you choose, no matter how close together they are, a wavelength, frequency, or amplitude can exist at a level between the two that you chose ... which is a pretty good working description of an analog quantity.

How are you able to change the intencity of a sound wave?
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. Better control the sound pressure level SPL.

What are the 5 examples of scalar quantity?
-- temperature -- cost -- speed -- wavelength -- frequency -- brightness -- pitch -- hardness -- refractive index -- mass -- time -- volume
If a sound seems to be getting louder which of the following is probably increasing intensity frequency wavelength or speed and sound?
The sound will get louder when the amplitude of the sound pressure increases. 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 does velocity consist of?
Velocity is a vector quantity and is defined by direction and amplitude, unlike a scalar quantity like speed, which is defined by only amplitude.

What are four qualities of tone?
Amplitude - perceived in terms of loudness /dB/ - the greater the amplitude is the louder the sound. Frequency - the number of oscillations per second. the higher the frequency is the higher on scale of pitch. It perceived in terms of pitch /Hz/ Simplicity/complexity - combination of amplitude and frequency. complex sound waves involve waves of different frequencies superimposed to one another. it is perceived as Quality of sound. Wave lenght - duration of time. reflection of sound wave : Quantity /m per sec/
