Two waves on one string are described by the wave functions y1 = 2.5 cos(3.0x â 1.5t)
y2 = 5.0 sin(4.5x â 2.5t)
where x and y are in centimeters and t is in seconds. Find the superposition of the waves y1 + y2 at the following points. (Remember that the arguments of the trigonometric functions are in radians.)
A cm x = 1.00 cm, t = 1.00 cm
Bcm x = 1.00 cm, t = 0.500 cm
Ccm x = 0.500 cm, t = 0 cm

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
