আলোক শক্তি থেকে শব্দ শক্তি: কীভাবে রূপান্তর করা যায়, উদাহরণ এবং তথ্য

In this article, we shall discuss how to convert sound energy to light energy along with examples and detailed facts.

There are very few direct methods to convert the sound energy to light energy while there are some indirect methods to which the sound energy is transformed into some other form of energy before converting it to light energy.

How is sound energy converted to light energy?

Sound energy is vibrational energy and needs a medium to travel through.

The vibrations produced in the molecules of a system induce the flow of charges in the conductor thus producing the electrical energy. The vibration also introduces the frictional energy which generates the radiant energy.

Sound Energy to Light Energy Examples

এখানে একটি তালিকা examples of sound energy to light energy that we are going to discuss further in this topic:-

মন্তিস শ্রিম্প

These shrimps are found in seawater and are locomotive at a very high speed and use sonic shock waves to catch their prey.

The molecules in the water collide with each other radiating the energy in the form of light for a few picoseconds.

Hitting Hammer on the Nail

Upon hitting the hammer on the nail the শব্দ শক্তি is produced. The surface of the hammer and the nail rubs together giving frictional energy. A part of the energy is lost in the form of heat. The excitation of the electron produces the spark due to heat energy.

বজ্রপাত

As the ions of water molecules get charged, they are ready to discharge the electrons cloud producing a loud noise of thundering. When the electrons get discharged they emit the energy in the form of light energy.

It releases a huge amount of energy and heat energy radiating the light energy. This leads to the emission of hazardous gases and particles in the atmosphere unhealthy for breathing.

আগ্নেয়গিরির অগ্ন্যুত্পাত

As the magma erupts on the Earth’s surface making the cleavages on the surface or mountain cliff, the শব্দ শক্তি সৃষ্ট. The light energy is given out by the excitation of the particles from the magma.

জ্বলন্ত কাঠ

The combustion of wood produces a sound of low frequencies generating the pressure difference and releasing the heat energy in the surrounding. The combustion of the wood gives out light energy.

ঢালাই

The welding produces a glow of light due to the excitation of electrons from the metal rod used for welding.

This produces sound energy while hammering and as the energy is released during the excitation of electrons.

Piezoelectric Material

This is used for the piezoelectric effect in the material which converts the sound energy to the electrical energy which can then be converted into light energy. The sound waves are incident on the piezoelectric material that introduces the vibrations of the molecules in the material generating the electrical energy.

LED Bulb with Transducer

The transducer is used to convert sound energy into various forms of energy. The sound waves can be converted into electrical energy using a transducer which is further used to radiate the LED bulbs giving the light energy.

Streetlight using Rectifier Bridge

The vehicles migrating on the street produce a sound. The sound wave incident on the piezoelectric material imposes a pressure thus resulting in the generation of electric current which is rectified by the rectifier bridge circuit radiating the streetlight.

Musical Lights

The serial LED light blinks as per the rhythm of the music. It ব্যবহারসমূহ electrical signals or a microphone to send signals to the light display.

বাতচক্র

The blowing wind accelerates the wind turbine into ঘূর্ণন গতি.

The rotation of the propellers undergoes wind abrasion and friction producing sound energy. This is converted to electrical energy by the generator. This is supplied to radiate the electric bulb.

ম্যাচস্টিকস

On rubbing the পটাসিয়াম lead of the matchstick on the surface of the box the sound energy is produced due to friction. This is then converted into light energy as the matchstick catches fire.

জলের টারবাইন

সার্জারির যান্ত্রিক শক্তি of the water produces sound energy when turned on the turbine. সার্জারির যান্ত্রিক শক্তি is converted into electrical energy by the generator and is used in the household supply.

মোটর

The sound energy is produced as the motor starts rotating. এই যান্ত্রিক শক্তি of the motor is converted into electrical energy which can be used to convert into light energy.

উত্পাদক

The coil in the generator perturbs the magnetic flux line thus it starts vibrating producing sound energy. The generator generates electrical energy that can be converted into light energy.

Igniting Stones

You rub the surfaces of the rocks across each other, and as the free electrons get heat energy due to friction, they start exciting and radiate light.

সচরাচর জিজ্ঞাস্য

How does sound energy generate?

The sound energy traverses through the longitudinal wave.

Sound energy is generated by vibrational motion. The vibration produces longitudinal waves setting the molecules into back and forth motion.

How does sound energy propagate?

The sound wave transmits the energy to the molecules in the medium through which it is propagating.

The energy acquired by the molecules in the medium is transferred to each subsequent molecule oscillating the molecules back and forth in the longitudinal wave.
