Awave is produced from a vibrating string on a violin. two observers are standing 20 m and 40 m away from the musician. the observer that is further away states that the violin sounds quiet but the other observer disagrees. what best explains the different experiences of the two observers?

a) the energy of the sound wave decreased as it moved away from the source.

b) the energy of the sound wave increased, then decreased as it moved away from the source.

An initially unpolarized light if intensity 500 w/m^2 passes through four polarizers. the transmission axis between adjacent polarizers is 45∘. what percentage of the initial intensity is transmitted by the system?

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
