If the source is giving out a power of W watts equally in all directions, the power density at a distance of R is given by:
W / (4.pi.R-squared) watts per square metre.

The rate at which light energy flows through a given area of space is referred to as its?
The rate at which light energy flows through a giver area of space is referred to as intensity
When electrical current flows through the metal filament of a light bulbelectrical energy is coverted to?
When electrical current flows through a lightbulb (whether it's CCFL, halogen, or incandescent), the trade-off is light and heat energy.
What type of energy is when you plug in a light bulb?
To plug it in, you use your muscle energy. When current flows through the bulb,electrical energy converted to the heat and light energy in the bulb.
What happens to the energy when you turn on an electric lamp?
Electricity flows through the filament, resistance in the filament causes heat and light energy to be created.
Why don't light waves need a medium?
Light wave flows as a form of radiation. One of the basic characteristics of radiant energy is it don't need a medium. But If it flows through a medium, it won't raise the temperature of medium.
The rate at which light energy flows through a given area of space is referred to as its?
The rate at which light energy flows through a giver area of space is referred to as intensity
The rate at which light energy flows through a given area of space is reffered to as its?
The answer is 'luminous intensity' which, in SI, is expressed in lumens.
When electricity flows through a light bulb it is converted into what two forms of energy?
kinetic energy and light energy.
What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
When electric energy flows through the metal filament of a light bulb energy is converted to?
Heat, which then produces light.
When electric flows through the mental filament of a light bulbelectrical energy is converted to?
The electrical energy is converted to both heat and light energy.
When electrical current flows through the metal filament of a light bulbelectrical energy is coverted to?
When electrical current flows through a lightbulb (whether it's CCFL, halogen, or incandescent), the trade-off is light and heat energy.
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
When electricity flows through the metal filament of a light bulb electrical energy is converted to?
Heat, which then produces light.
What type of energy is when you plug in a light bulb?
To plug it in, you use your muscle energy. When current flows through the bulb,electrical energy converted to the heat and light energy in the bulb.
What happens to the electricity as it flows through the closed circuit?
Some is changed into light and heat energy and some continues through the curcuit
What happens to the energy when you turn on an electric lamp?
Electricity flows through the filament, resistance in the filament causes heat and light energy to be created.
