Answer:
- Light is bounced back at same angle (Classical Reflection)
- Light penetrates medium at different angle due to different material densities (Refraction)
Light bounces at different angles in periodic grid (Reflected Diffraction)
Light enters medium at different angles through a grid (Transmission Diffraction)
- Light EMF field looses one axis component (Polarized filter)
Explanation:
Reflection is a phenomenon in which waves (light included) bounce back from an obstacle at the same angle of incidence
Refraction is the change in the angle of a wave as it enters the interface of two media. The change in angle is due to the difference in the densities of the two media.
Reflected diffraction occurs when an optical component with a periodic grid, splits, and diffracts light into several beams travelling in different directions. The light light bounces at an angle in the periodic grid.
Transmission diffraction is dispersion a beam of various wavelengths into a spectrum of associated lines due to the principle of diffraction. In this type of diffraction, light enters medium at different angles through a grid.
Polarized filters removes one field from the incidence electromagnetic wave like light, leaving it to vibrate in only one plane.
Answer: Batteries have three parts
Explanation:
Batteries have three parts, an anode , a cathode , and the electrolyte. The cathode and anode the positive and negative sides at either end of a traditional battery are hooked up to an electrical circuit. The chemical reactions in the battery causes a build up of electrons at the anode.
A effective ground-fault current path is an intentionally constructed, low-impedance electrically conductive path designed and intended to carry current during ground-fault conditions from the point of grounding on a wiring system to the electrical supply source.
<h3>Is earth an effective ground fault current path?</h3>
- Sticking the wire in the ground is not sufficient since the earth is not thought to be a reliable ground-fault current channel.
- The electrical system of a building or other structure is based on grounding.
- To give a fault current a secure path to travel, grounding is used.
- When installing switches, light fixtures, appliances, and receptacles, a complete ground route must be kept.
- The undesired current flow trips circuit breakers or blows fuses in a system that is correctly grounded.
- Through the use of a grounding bank, effective grounding maintains voltages within predetermined limits during a line-to-ground fault (short-circuit condition).

Answer:
Explanation:
Heat engine
Heat engine is a device which produce work while consuming some amount of energy .This engine works in cycle.In other words we can say that Heat engine is a device which covert thermal or chemical energy in to mechanical energy and after that this mechanical energy can be use for producing mechanical work.
Heat engine takes heat from high temperature and rejects heat to lower temperature and producing work.
We know that efficiency given as
From diagram we can say that
So efficiency
