Using biprism interference pattern can be produced. Therefrom the band width beta is to be measured. Now using the formula, beta = lambda*D/d

Here lambda is the required wavelength of the source light. D is the distance of the screen from the virtual sources. d is the distance between the two virtual coherent sources. Knowing beta, D and d, required lambda could be calculated.

You can achieve this by connecting a mechanical arm or lever to a motor that can move it in a pressing motion. Then, program the motor to move the arm down to press the button for a set amount of time, followed by moving it back up to release the button. This sequence can be repeated continuously for 30 seconds.

People invented motion lights as a way to enhance security and safety around homes and buildings. By automatically turning on when motion is detected, they help deter potential intruders and provide visibility in dark areas. Additionally, they save energy by only operating when needed.

The first step is amplification of the sound that is picked up by a microphone. This usually consists of a basic 'pre-amp' section which brings the audio signal up to workable levels, and a secondary amplification which makes the signal strong enough to be processed by the recoding circuit.

Like charges repel each other, while unlike charges attract each other. This occurs due to the electric force, which acts between charged particles. Like charges have the same sign of charge (positive or negative), while unlike charges have different signs.

Frequency scintillation is a phenomenon in radio wave propagation where the frequency of a signal fluctuates rapidly due to variations in the ionosphere or other environmental conditions. These fluctuations can cause distortions in the signal, affecting communication and navigation systems. Frequency scintillation is often observed in satellite communications and radio astronomy.

Charge imbalance refers to a situation where there is an unequal distribution of positive and negative charges within a system. This imbalance can lead to the creation of an electric field and potentially result in electrical currents flowing to restore equilibrium.

Carbon has unique properties that make it challenging to use as a semiconductor material. It can exist in multiple structures (diamond, graphite, etc.) with varying electrical properties, making it difficult to control and predict its behavior as a semiconductor. Additionally, fabricating carbon-based semiconductor devices is technologically complex and expensive compared to traditional semiconductor materials like silicon.

If the two pith balls were held together, they would acquire the same charge due to the contact between them. When released, they would then repel each other due to their like charges, causing the pith balls to move apart.

Bullet trains use electric motors powered by overhead lines or onboard batteries to propel the train forward. The trains also use magnetic levitation or steel wheels on steel rails to reduce friction and increase speed. The streamlined design of the trains minimizes air resistance, allowing them to reach high speeds efficiently.

Just place a piezo electric crystal in your shoe then due to alternate change of your feet causes mechanical stress and strain .Inverse piezo electric effect states that when stress and strain is given along mechanical axes it creates electricity along electrical axes.Thus piezo electric crystal converts mechanical energy to electrical energy.

The Henry (H, unit of inductance) is only known as the Henry.

As an SI unit, it has the usual multiples (kilo = 1000, rare) and milli (1/1000), micro (1/1000 000) and nano (1/1000 000 000).

The nanohenry is not common except in VHF/UHF/SHF equipment.

Electrons can travel through a vacuum because there are no atoms or molecules to collide with, allowing them to move freely. In air, electrons collide with the molecules present, which disrupts their movement and prevents them from traveling efficiently.

Not always. This null point can be obtained practically on any part of the wire, as this simply depends upon the segmental thicknesses of the wire, the different resistances, cells or other appliances attached on its different segments.

Davy discovered the element potassium by isolating it through the electrolysis of molten potassium hydroxide using a voltaic pile, a type of battery, in 1807.

THE ULTRASONIC WAVES have constant velocity in homogeneous medium. Many modes of vibration. High resolution,used for flaw detection Sonic beam and highly energetic. reflection and refraction in interface.so elastic

The SYMBOL for charge is q, the standard UNIT for charge is coulomb, and the abbreviation for the unit is C

The purpose of a battery is to provide power/electricity to the circuit or other object.

to provide energy for the current to flow

The electrical cell/battery is designed to store energy in chemical form, and to

deliver it in electrical form when required.

The refractive index of diamonds is approximately 2.42. This high refractive index contributes to the diamond's brilliance and sparkle when light enters and exits the stone.

At the positive electrode, oxygen gas was produced.

Current is measured by amperes.
