What is phonon effect?
The phonon effect refers to the interaction of electrons in a crystal lattice with lattice vibrations. This interaction can cause scattering of electrons, affecting the electrical and thermal properties of the material. Phonons play a significant role in determining the overall behavior of materials at the quantum level.
Why efficiency of solar photovoltaic cell is not 100 percent?
Because semiconductors such as silicon are indirect bandgap semiconductors, so some of the light energy is wasted as lattice vibrations (phonons).
Why do some isomers lack optical activity?
Some isomers lack optical activity because they have a plane of symmetry or a center of symmetry that results in the molecule being superimposable on its mirror image. This makes them achiral and unable to rotate the plane of polarized light, thus lacking optical activity.
What are some examples of items with low conductivity?
Thermal resistance: diamond Electrical resistance: copper Optical resistance: quartz
Does a substance having high optical density have to have a high physical density?
No, a substance with high optical density does not have to have a high physical density. Optical density refers to how much a material can absorb or reflect light, while physical density refers to the mass of the material per unit volume. These properties are not directly related.
What is the smallest unit of sound wave energy?
The smallest unit of sound wave energy is called a phonon. Phonons are quantized units of vibrational energy in a crystal lattice or in any elastic medium which carries sound.

What are some common optical illusions questions that people often ask?
Some common optical illusion questions that people often ask include: "How does an optical illusion trick our brain?" "Why do some people see optical illusions differently?" "Can optical illusions be used to study the brain?"
What is some information on optical illusions?
optical illusions are an object causing false impressions
What is an easy definition of the optical axis?
An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens or microscope..
What is optical hardware?
Optical networking hardware entails the various components used in optical technologies. Some of the common hardware include routers, optical fiber, electronic devices and so much more.
What is optical track pad?
An optical trackpad senses touch, like on the HTC desire. and some Blackberrys.
What is some materials for the optical illusions?
hologram

What uses a device that emit and sense light to detect the mouse's movement?
Optical mouse: Most desktop computer users today have some type of optical mouse, which uses devices that emit and sense light to detect the mouse's movement.
What are some words that start with opt?
Some words that start with opt are: option, optimal, optician, optimize.
Why efficiency of solar photovoltaic cell is not 100 percent?
