What is Light?

For a human to be able to see properly, we need light. According to the American Museum of Natural History, light crosses into the retina on the back of the eye. Millions of light-sensitive cells (rods), and cones cover the retina in the human visual system. It will send notifications to the brain when it catches the light.

Hence, no one can see anything in pitch black, even with healthy eyes. Light is a visible electromagnetic spectrum that can extend to 780 nanometers. Light allows the human eye to see or makes objects visible.

Some scientists also define it as visible radiation to the human eye. Photons, which are tiny packages of energy, are located in light. Many research found that this element always moves in a straight line. Light is a basis of illumination, whether natural (fire, sun) or artificial (gadget screen, lamp).

What is Sound?

In physics science, the definition of sound is a vibration that multiplies as an acoustic ripple through various transmission mediums such as a gas, liquid, or solid. In human physiology and psychology, sound is the response or effect of such waves and their perception by the brain. In general, sound has these characteristics.

• Sound is a type of energy that comes from the vibration of matter, which travels through a medium such as air, water, or solids. These vibrations cause the particles of the medium to compress and expand, creating a wave-like pattern that travels through the medium until it reaches the human ear.
• Even though sound can travel through various mediums, it cannot pass through a vacuum. Hence, we cannot hear a sound in outer space.
• The frequency of the sound wave, measured in Hertz (Hz), determines the pitch of the sound. Higher-frequency waves construct higher-pitched sounds, while lower-frequency waves produce a similar pitch.
• The amplitude of the sound wave, measured in decibels (dB), determines the volume or loudness of the sound.
• Human ears can detect sounds within a range of frequencies, typically between 20 Hz and 20,000 Hz. Sounds outside this range are either too low or too high for a human to hear.

Are Light and Sound Related?

Based on the Grainger College of Engineering, light doesn't affect sound. However, these two elements share similar characteristics, such as both energies travel in waves.

Light has a faster speed than sound. Meanwhile, sound has longer waves than light. They also have different types of waves, where light is electromagnetic waves and sound is mechanical waves which need a medium to travel.

While light and sound are different, they interact with each other in various ways. For example, when light passes through a medium, such as air, it can cause the air molecules to vibrate and produce sound waves. This fact is known as the photoacoustic effect.

It is a formation of sound waves which follow the light absorption in a material sample. Some experts also called it the optoacoustic effect. In a similar moment, sound waves can cause objects to vibrate, which generates light waves if the matter is hot enough. This condition is known as sonoluminescence.

It is when a tiny bubble gas is suspended and driven in a solution of liquid in ultrasonic frequencies, which results in bubble cases, cavitation, and light emission. In conclusion, light and sound are two different forms of energy that can interact with each other in various ways, but they have different properties and travel through different mediums.

Why Should We Learn About Light and Sound?

Some people might overlook the importance of light and sound since we can easily find them. However, these two energies have an essential role in human life.

• Most young students learn about light and sound in elementary school. They study the basic information about them. At this stage of education, young children will realize the function of light in helping humans see and perceive their surroundings.
• They will also learn how sound allows a human to hear and communicate.
• Light also affects the physiology, psyche, and biological processes of humans. It supports us in distinguishing the details in our surroundings, such as colors, movement, and brightness. You can know it through phenomena such as transparent, translucent, and opaque phenomena on an object.
• Sounds also help us to recognize the characters, place, and time of our surroundings.
• The proper ability to listen to sound also improves how someone perceives what they see.

How to Appropriately Utilizing Light and Sound?

It is in human nature that we make use of the natural resources and energy around us. However, we should use them wisely and not violate them, which can lead to them destroying the Earth.

We can apply some strategies to use light energy, such as reducing the wattage, avoiding multiple fittings, using solar energy, keeping the lights neat, and more. In utilizing sound, we also should be careful not to disturb others.
