Absorption of lightExamples

REED Instruments offers a broad selection of digital light meters. REED light meters are used every day in various applications including: to ensure work environments meet OSHA standards, to determine optimum light levels for a film scene or photography, and during the verification process of new lighting system installations on construction projects. Whether you're looking for a compact meter for basic light measurement applications or you require a system for long-term continuous monitoring, REED Instruments has a light meter to meet your needs.

Absorption of lightin wavelength

The R1630-KIT comes equipped with the required tools for continuous long-term remote monitoring. This kit includes a Data Logging Bluetooth Smart Series Light Meter (R1630), Tripod (R1500), and Soft Carrying Case (CA-05A).

Contrary to the absorption of light, transmission and reflection of light occur when the natural frequency of the vibration of electrons do not match the frequencies of the incident light. In such cases, when the light wave strikes the objects, the electrons of the object begin to vibrate. The electrons vibrate for a brief period of time with small amplitude after which the energy is re-emitted as a light wave. If the object under consideration is transparent, the vibrations of the electrons are passed on to the neighbouring atoms and are re-emitted from the opposite side of the object. In such cases, the light is said to be transmitted. If the object is opaque, the vibrations of the electrons are not passed in bulk, rather the electrons of the atoms vibrate for a short period of time and are re-emitted as a reflected light wave from the surface of the object.

At specific frequencies, the electrons of the atom tend to vibrate. When a light wave of the same natural frequency is incident on the atom, the electrons of that atom will be set into vibrational motion. During vibration, electrons interact with neighbouring atoms in such a manner it converts the vibrational energy into thermal energy. Hence, we can conclude that the selective absorption of light occurs when the frequency of the light matches the frequency at which the electrons in the atoms vibrate. Different atoms and molecules possess different natural frequencies of vibration, hence they will selectively absorb different frequencies of visible light.

Real-time data logger with integrated SD memory card measures/records ambient light levels in Foot Candles or Lux and contact temperature with optional type J/K thermocouple probe.

Absorption of lightin physics

Light is the only electromagnetic radiation that is visible to the human eye. It is made of little packets of energy known as photons. When a light wave is an incident on an object, a number of things can happen. It is either absorbed, transmitted or reflected. The manner in which visible light interacts with an object depends on the frequency of light and the nature of the atoms of the object. In this article, we will discuss how and why the light of certain frequencies are selectively absorbed, reflected and transmitted.

The colour of the objects that we see is largely due to the interaction of the object with the incident light. The colour of the object is not within the object itself. Rather, it is in the light that shines upon it. When the light of a certain frequency falls on the object, the light frequencies that are absorbed never make it to our eyes. Only the frequencies of incident light that are reflected or transmitted contributes to the colour of the object. So if an object absorbs all the frequencies of the light wave except the frequency associated with green, then the object appears green.

Absorption of lightequation

This view presumes that the appearance of an object is independent of the colours of light which illuminate the object. It must be noted that the same objects appear to be of different colour under a different light. Hence, the colour of an object is strictly not due to the object’s ability to produce a colour. The only role the object plays in determining its appearance is by absorbing certain wavelengths of the incident light.

This portable solar power meter is used to measure the amount of solar irradiance in watts per square meter (W/m²) or BTU/(ft²xh).

2. One common historical belief was that coloured objects in nature produce small particles (perhaps light particles) that subsequently reach our eyes. Different objects produce different coloured particles, thus contributing to their different appearance. Is this belief accurate or not? Justify your answer.

When the room lights are turned off, any object present in the room appears black. The colour of the object depends on the frequency of the light that is reflected in the observer’s eye. Without light, there is no reflected light as a result of which the green shirt appears black.
