Select the best answer from the choices below. Light has many properties of waves but sometimes it also behaves like: A photon Polarized light ultraviolet rays schem of particles

The correct option is;

Stream of particles

Explanation:

Light can be observed to behave as stream of particles in the physical phenomenon of blackbody radiation and photoelectric effect whereby electrons are ejected by the impact of light such that the number of electrons ejected is a function of the amount of photons transmitted which are absorbed by the electrons before they can be ejected

The energy of the photons depends on the frequency of the light source of the photons, while the electrons are ejected when the energy of the photon is up to their threshold value

As such light can also be considered as behaving as a stream of particles called photons.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
