• Visible Light Reflection and Transmission. Reflection and transmission of light waves occur because the frequencies of the light waves do not match the natural frequencies of vibration of the objects. When light waves of these frequencies strike an object, the electrons in the atoms of the object begin vibrating.

When light moves through a transparent (or semi-transparent) material, it can be transmitted, absorbed, or reflected. The transmittance of a material is the proportion of the incident (approaching). In this series of games, your students will learn about the electromagnetic spectrum and how light travels. The Reflection, Absorption, and Transmission of Light learning objective — based on NGSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research. Scroll down for a preview of this learning objective’s games. Transmission Line Transmission lines are carefully monitored, real-time substation monitoring may, or may not, occur and limited metering is typically applied to distribution feeders or circuits to monitor electricity distribution voltage and other values.

Concepts Covered

Light interacts with matter. Different materials can reflect, transmit, or absorb different amounts and wavelengths of light.

When electromagnetic waves transfer energy, they generate light. They are measured by their wavelength, frequency, and speed. For example, each color in the visible light spectrum — red, orange, yellow, green, blue, indigo, and violet — represents a different wavelength and frequency.

Gamma rays, x-rays, ultraviolet, infrared radiation, microwaves, radio waves, and visible light make up the electromagnetic spectrum. They all travel at the same speed — the speed of light — in a vacuum, but when they come into contact with matter, they slow down.

All objects reflect and absorb some light. Some also give off their own visible light, but most are visible because they reflect light into our eyes. An object’s color depends on which wavelengths of light it absorbs and which it reflects.

Some objects transmit light, meaning light passes through them. Opaque objects transmit little or no visible light, translucent objects transmit some, and transparent objects transmit almost all, which is why we can see through them.

Some objects that transmit visible light absorb other wavelengths of light. For example, sunglasses are designed to transmit visible light and absorb ultraviolet light, protecting your eyes.

Data transmission is a means of transmitting digital or analog data over a communication medium to one or more devices. It allows the transmission and communication of devices in different environments: point-to-point, point-to-multipoint, or multipoint-to-multipoint.

Data transmission can either be analog or digital, but is mostly earmarked for sending and receiving digital data. As such, data transmission is also referred to as digital transmission or digital communications.

It works when a device aims to transmit a data object or file to one or multiple recipient devices. The digital data comes from the source device in the form of digital bit streams. These data streams are positioned over a communication medium for transmission to the destination device. An outward signal can either be baseband or passband.

Aside from external communication, data transmission may be done internally, between different parts of the same device. The sending of data to a processor from the random access memory (RAM) or hard disk is a form of data transmission.

Types of Data Transmission

What Is Transmission In Science Terms

• Parallel transmission – Several bits are transmitted together simultaneously within one clock pulse rate. It transmits quickly, as it utilises several input and output lines for sending the data.
• Parallel transmission uses a 25-pin port with 17 signal lines and 8 ground lines. The 17 signal lines are divided as follows:

• 4 lines – initiate handshaking
• 5 lines – communicate and notify errors
• 8 lines – transfer data

Comparison between Serial and Parallel Transmission

Types of Serial Transmission

There are two types of serial transmission – synchronous and asynchronous. Both of these transmission methods use bit synchronisation.

Bit synchronisation is necessary to identify the beginning and end of the data transmission.

Bit synchronisation supports the receiving computer to recognise when data begins and ends during a transmission. Therefore, bit synchronisation offers timing control.

• Asynchronous Transmission – In asynchronous transmission data moves in a half-paired approach, 1 byte or 1 character at a time. It sends the data in a constant current of bytes. The size of a character transmitted is 8 bits, with a parity bit added at the beginning and at the end, making it a total of 10 bits. It doesn’t need a clock for integration—rather, it utilises the parity bits to inform the receiver how to translate the data. It is straightforward, quick, and cost-effective, and it doesn’t require 2-way communication.
• Synchronous Transmission – In synchronous transmission, data moves in a complete paired approach in the form of chunks or frames. Synchronisation between the source and target is required so that the source knows where the new byte begins, since there are no spaces between the data. This method offers real-time communication between linked devices.
