Both a wave and a particle description of light are possible. The dual character of light has been highlighted in particular by two investigations.
<h3>What is made up of Light?</h3>
Photons are electromagnetic field bundles that contain a set amount of energy and are the building blocks of light. Photons can be counted or even individually measured with sensitive enough studies.
Both a particle and a wave can be used to describe light. The dual nature of light has been demonstrated through two tests in particular. The particles we refer to as "photons" when imagining light as being composed of them are small. A certain quantity of energy is carried by each photon, which has no mass.

Answer:
In the shooting scene, you'd be able to collect the shell of the bullet and that would be one step to find out what type of gun the perpetrator used.

A lo largo de la historia y hasta el surgimiento del movimiento feminista, las mujeres se encontraron en un lugar relegado en la sociedad. Varios son los ejemplos de esta situación, entre los que podemos mencionar:
-el sometimiento ideológico, al prohibirseles el voto hasta bien entrado el siglo XX. Hasta hace 100 años atrás, las mujeres no tenían la posibilidad de expresarse en las urnas.
-las mujeres, en sus trabajos, aun hoy en día sufren discriminación salarial: cobran menos que los hombres por el mismo trabajo realizado.
-la total dependencia de los labores domésticos, los cuales son otorgados en forma egoísta a la mujer por parte del hombre. La mujer muchas veces ocupa un rol de "sirvienta" al servicio del hombre, completando todos los quehaceres de la casa sin ayudas.
-el sometimiento económico, por el cual en el pasado no se permitía a la mujer trabajar, con lo cual se la hacia absolutamente dependiente económicamente del hombre.
-la desigualdad en los puestos de poder entre hombres y mujeres, la cual se ve explicitada en la proporción de mujeres con altos cargos políticos en comparación con la cantidad de hombres en los mismos.
Collective bargaining is the process in which working people, through their unions, negotiate contracts with their employers to determine their terms of employment, including pay, benefits, hours, leave, job health and safety policies, ways to balance work and family, and more. Collective bargaining is a way to solve workplace problems.
