The intensity of light is measured in lumens.
The amount of energy in light can be measured in any unit of energy (BTU, calories, Joules, etc.)
The energy per unit time can be measured in any unit of power (Watts, horsepower etc.)
All of these are independent of specific classes of coordinate systems and hence "scalar".
What else can I help you with?
Flow rate of mass is vector or scalar?
The flow rate of mass is a scalar quantity since it only has magnitude and no direction associated with it. It represents the amount of mass passing through a given area per unit time.
Is surface tension scalar or vector?
surface tension is a scalar quantity because it has no specific direction.
Name the physical quantity whose SI unit is JC-1Is it a scalar or a vector quantity?
The physical quantity with the SI unit JC^-1 is the electric permittivity. It is a scalar quantity because it describes the ability of a material to store and transmit electrical energy.
Is pressure a scaler quantity?
Pressure is no vector. Pressure is a scalar. Pressure-gradient is a vector.why pressure is a scalar
What is speed a scalar or vector quantity?
scalar
Is intensity of light scalar or vector quantity?
I think light could not be recoginzed as a vector. However, I think the light intensity could be devided into the x-y axises.
Is frequency a scalar or vector unit?
Frequency is a scalar since it has magnitude only.
Is pressure scalar or vector quantity?
Pressure is a scalar quantity. It is defined as the force per unit area and only has magnitude, not direction.
Is a electric potential scalar or vector?
Electric potential is a scalar.
Is light vector or scalar?
Light is a scalar. This is the reason we talk about the speed (scalar) of light. This is al;so the reason the Michelson-Morley Experiment was a deemed a failure, though it was a success. M-M assumed as did most scientists that light was a vector and would compound like a vector. When light had the same speed in all directions, which a vector would not do, the experiment was said to fail, when in fact it succeeded in showing light to be a scalar. What failed was the expectations of the experimentors and rather accept that light was a scalar they invented the shrinking of space in the direction of motion.Light is related to the fourth dimension of Quaternion Space:Q= r +Ix +Jy +Kzwhere I, J and K are vectors and the scalar is r=ct where c is the speed of light and t is time. Light c is related to the real scalar distance r=ct.
Electrostatic potential is a Scalar Quantity or Vector Quantity?
Electrostatic potential is a scalar quantity. It represents the potential energy per unit charge at a given point in an electric field.
What properties of a scalar quantity?
They only have a magnitude , no direction.
Is temperature vector or scalar?
Temperature is a scalar quantity. It has magnitude but not direction.
What is the formula of scalar quantity?
Scalar quantity is a physical quantity that has magnitude only, without any direction. It is often represented by a number with a unit. There is no specific formula for scalar quantity as it is independent of directions. Examples of scalar quantities include mass, temperature, and speed.
Flow rate of mass is vector or scalar?
The flow rate of mass is a scalar quantity since it only has magnitude and no direction associated with it. It represents the amount of mass passing through a given area per unit time.
Is refractive index scalar or vector?
Refractive index is a scalar quantity because it describes how light propagates through a medium by bending, or refracting, without considering a specific direction of travel.
Is intensity of a wave a vector or a scalar quantity?
Intensity of a wave is a scalar quantity because it only has one value that represents the amount of energy transferred per unit area per unit time. It does not have a direction associated with it like a vector quantity.
