Optical Properties

A component of an electromagnetic wave is simply a rapidly fluctuating electric field

• Electron Transitions
• Electronic Polarization
• Electromagnetic Radiation
• Electromagnetic Spectrum

What optical property is responsible for the bending of light as it passes through a medium with a different optical density?

• Absorption
• Refraction
• Reflection
• Transmission

Some materials are capable of absorbing energy and then reemitting visible light in a phenomenon called

• Photoconductivity
• Translucency
• Luminescence
• Opacity

What does the acronym of "LASER" stand for?

• Light Amplification by Stimulated Emission of Radiation
• Luminous and Synchronized Emission of Radiation
• Longitudinal Amplitude of Spectral Energy Radiation
• None of the above

Photoconductivity is a phenomenon observed in certain materials. Which of the following statements accurately describe photoconductivity? Choose two answer

• Photoconductivity refers to the increase in electrical conductivity of a material when exposed to light.
• The process involves the generation of electron-hole pairs due to the absorption of photons.
• Photoconductivity is a phenomenon exclusive to insulating materials.
• In photoconductors, incident light causes a decrease in electrical conductivity.

The ability of metals to allow light to pass through without significant absorption.

• Reflection
• Transmission
• Photoconductivity
• Opaque

What are the two consequences of electronic polarization? Choose two answer

• Absorption
• Refraction
• Reflection
• Transmission

The perceived color of a metal is determined by

• Density and Weight
• The temperature at which it was last heated
• The arrangement of atoms in the crystal lattice
• Spectral composition of the reflected light

Light is transmitted diffusely, there is some scattering within the interior of the material.

• Transparent
• Translucent
• Transmission
• Refraction

What characterizes an opaque material

• It allows light to pass through easily.
• It transmits some light but scatters the rest.
• It reflects and absorbs light, preventing transmission.
• It exhibits perfect transparency under all conditions.
