Two loudspeakers, L1and L2, have the same frequency and
are in phase with each other.
An interference pattern is
produced

At position P, which is the same distance from both loudspeakers, there is a maximum. The next
maximum is at position R, where L R = 2.8 m and L R = 2.5 m.
The speed of sound in air is 340 m st. The frequency of the sound emitted by the loudspeakers is:
(A) 2.0 x 102 Hz
(B) 2.3 x 102 Hz
(C) 5.7x 102 Hz
(D) 1.1 x 103 Hz

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

Which of the following is a transformer used for? alternate a voltage produce a voltage increase or decrease a voltage eliminate a voltage

Which wave would cause destructive interference at every point of the wavelength and completely cancel out the wave?
