Waves transfer , not the with it. A causes particles in matter to move back and forth at right angles to the direction in which the wave travels. High points in a transverse wave are called . Low points are called . A wave causes particles in matter to move back and forth along the same direction in which the wave travels. The places in a longitudinal wave in which the coils are squeezed together are called . The places in the wave in which the coils are spread apart are called . The of a transverse wave is the distance between two adjacent crests or two adjacent troughs. The of a compressional wave is the distance between two adjacent compressions or rarefactions.. The of a wave is the number of wavelengths that pass by a point each second. Frequency is measured in units of . The of a wave depends on the medium in which the wave travels. To make a wavelength of rope shorter, one should shake the rope at a frequency. The speed of a wave can be found using the equation . As the wavelength of a wave increases, the frequency of the wave . The energy of a wave depends on its .

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
