When 60 W means that W joules of energy are transferred into the bulb each second. In use how much energy is given out by the bulb each second?
The light bulb will use electrical energy at the rate of 60 W (60 J/s), and it will emit that energy, also at the rate of 60 W.Note that in any real light bulb, only part of the energy is emitted as visible light. The remainder is mainly heat.
How many joules does it take to light a 60 watt light bulb for an hour?
60W = 60J/sec = 3600J/min = 216,000J/hr or 60W x 1hr = 0.6kWh = Your kWh rate * 0.6 If my kWh rate is $0.05 then it costs $0.03 to power a 60W bulb for an hour, other charges may apply in your area, you will have to look at your bill
What path does light take when to see an object?
When your eyes can detect images, light from a light source(s) is being reflected from the objects you see directly to your retina. For example, you are in a closed room with one overhead light fixture. The light from the light bulb is being filtered and scattered to light up some surfaces in the room. Light travels in a straight line. The shadow below a desk is where there is no direct light (no direct path to the light source). However, light scattered off the wall or chair will still reach below the desk, where you can still see a faded image. When you can see an image, bright or faded, it means that some light has reflected off that surface to reach your eyes. A bright image is seen when more light reaches that surface and reflects to your eyes than a fuzzy image. =========================
Why the speed of light has been quoted as being 'in a vacuum' yet the speed of sound is at a specific temperature?
Light will be transported without a medium. The speed of light is = 299 792 458 m/s. Sound need a medium to be transported. It's mostly air, where the temperature is important. The speed of air is 343 m/s at 20 degrees Celsius and 331.3 m/s at 0 degrees Celsius.
