Lux: The lux is a SI unit of illuminance and luminous emissivity that measures flux per unit area and is equivalent to one lumen for every square meter. It is indeed a measurement of the intensity of light that strikes or travels through a substrate in photometry.
Yes, that's correct! The lux (lx) is indeed a unit of illuminance in the International System of Units (SI). It measures the amount of luminous flux (or light) that falls on a surface area.Here's a breakdown of what lux measures:Definition: 1 lux is defined as 1 lumen per square meter (lm/m²).PurposRead more
Yes, that’s correct! The lux (lx) is indeed a unit of illuminance in the International System of Units (SI). It measures the amount of luminous flux (or light) that falls on a surface area.Here’s a breakdown of what lux measures:Definition: 1 lux is defined as 1 lumen per square meter (lm/m²).Purpose: It quantifies the intensity of light that reaches a surface or is emitted from a source over an area.Application: Lux is commonly used in lighting design, architecture, photography, and various industries where measuring light intensity on surfaces is important.For example:A surface illuminated with 1 lux would receive 1 lumen of light spread over each square meter of that surface.Higher lux values indicate brighter illumination, while lower lux values indicate dimmer illumination.Lux is a crucial measurement in photometry, helping to ensure appropriate lighting levels for tasks, comfort, safety, and aesthetic purposes in various environments.

See lessWhat is CGS and SI?
CGS and SI are two different systems of units used in physics and engineering:CGS (Centimeter-Gram-Second):Length: The unit of length in CGS is the centimeter (cm).Mass: The unit of mass in CGS is the gram (g).Time: The unit of time in CGS is the second (s).CGS is characterized by smaller base unitsRead more
CGS and SI are two different systems of units used in physics and engineering:CGS (Centimeter-Gram-Second):Length: The unit of length in CGS is the centimeter (cm).Mass: The unit of mass in CGS is the gram (g).Time: The unit of time in CGS is the second (s).CGS is characterized by smaller base units compared to SI, which can sometimes lead to more convenient numerical values in certain scientific calculations. However, it is less commonly used today compared to SI.SI (International System of Units):Length: The unit of length in SI is the meter (m).Mass: The unit of mass in SI is the kilogram (kg).Time: The unit of time in SI is the second (s).SI is the modern form of the metric system and is widely used in scientific and everyday contexts globally. It provides a coherent system of units that are internationally recognized and standardized.Both CGS and SI systems have their advantages and historical significance, but SI has become the preferred system in most scientific disciplines due to its simplicity, coherence, and global acceptance.

The concept of the proton, as a fundamental particle, does not have a single “father” in the same sense as a discoverer of a specific person. However, the discovery of the proton is attributed to several scientists who contributed to its understanding over time:Ernest Rutherford: He proposed the existence of the proton in 1917 based on his experiments where he bombarded nitrogen gas with alpha particles and observed hydrogen nuclei (protons) being emitted.Ernest Marsden and Hans Geiger: They conducted the famous gold foil experiment under Rutherford’s supervision, which provided evidence for the existence of a dense, positively charged nucleus (where protons reside) within the atom.Niels Bohr: He further developed the model of the atom based on Rutherford’s findings, incorporating the idea of protons and electrons in distinct energy levels.Therefore, while Rutherford is often credited with proposing the existence of the proton based on experimental evidence, it was a collective effort of several scientists working in the early 20th century to develop the concept and understanding of this fundamental particle.

In the context of electricity and electric current, “1 A” refers to 1 ampere, which is the SI unit of electric current. Electric current is the flow of electric charge carriers, such as electrons, through a conductor or circuit. One ampere (1 A) is defined as the amount of electric current that flows through a cross-sectional area of a conductor in one second when the electric charge of one coulomb passes through the conductor. It’s a fundamental unit in electricity, used to quantify the rate of flow of electric charge.

No, “volt” is not a standalone unit; rather, it is a unit of measurement for electric potential, electromotive force (emf), or electric potential difference. The volt is the SI unit of electric potential or electromotive force. It represents the difference in electric potential between two points of a conducting wire carrying a constant current of one ampere when the power dissipated between these points is one watt. In summary, “volt” measures electric potential difference or voltage, not a physical quantity like length or mass.
See lessWhat is 1 kilowatt-hour?
A kilowatt-hour (kWh) is a unit of energy commonly used to measure electricity consumption. It represents the amount of energy used by a device rated at 1 kilowatt (kW) over a period of one hour. In simpler terms, it's the energy consumed when a 1 kW appliance operates continuously for one hour. It'Read more
A kilowatt-hour (kWh) is a unit of energy commonly used to measure electricity consumption. It represents the amount of energy used by a device rated at 1 kilowatt (kW) over a period of one hour. In simpler terms, it’s the energy consumed when a 1 kW appliance operates continuously for one hour. It’s widely used by utility companies to measure and bill for electricity usage. For example, if you run a 1 kW appliance for 1 hour, you would consume 1 kWh of electricity.
