Chapter 18, Problem 73E

Interpretation Introduction

Interpretation:

The color of light that can be used to make selenium conductive needs to be identified

Concept Introduction:

Selenium (Se) belongs to group 6A in the periodic table and is a metalloid with properties between a metal and non-metal.

Electromagnetic radiation which is a composite of light of different wavelengths can interact with matter and affect its properties by the transfer of energy.

The energy (E) of a photon of wavelength (λ) and frequency (ν) is given by the Planck's equation:

  $\begin{array}{l}\text{E = hν}\\ \text{or, E = h}\frac{\text{c}}{\text{λ}}\text{ -----(2)}\end{array}$

Here,

h = Planck's constant = 6.626x10-³⁴Js
