18. which properties of light define light as a wave? (points: 5)

Light is an electromagnetic radiation. It has both particle and wave nature. As a wave, light has amplitude, wavelength and frequency. These factors define a wave. Also, light undergoes interference and diffraction which are wave phenomena. On the other hand, light some times behaves as a particle. It is composed of photons. Each photon is a quanta of energy. Photoelectric effect can be explained on the basis of particle behavior of light.

it should be -8.6 cm hope this out

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
