To absorb kinetic energy and dissipate the force of a crash, new cars have special safety features such as air bags and crumple zones. As these features deform, they increase the amount of time it takes for a person to stop or hit an internal object and therefore reduce the speed. Since kinetic energy is proportional to speed, this takes some of the energy out of the collision.

blsea [12.9K]
They are both right because you can note both things, I mean Raphael and Lucinda, both has a right statement or explanation about the wave. Wave by nothing is both for its wavelength and for its frequency. So Raphael and Lucinda are both correct because you can note both wavelength and frequency.
