Would a light stick be a good light source in a potentially explosive environment?
Yes
How would you hit the metal rod to create a longitudinal wave?
You would either position the object creating the shadow perpendicular to the light source or move it closer to the light source.
A red light source and a green light source shine on a white screen what color will the screen be explain answer?
It would be come a white light( it will show up to have a rainbow streak on the screen though)
What object absorbs all incident light?
An ideal black body would do that. In nature, the only actual such body would be a black hole.
What will happen to the shadow if a stronger light source is used?
The shadow would turn darker......
Is color a characteristic property of elements?
Color is due to the reflection of white light. If the light source changes then the apparent color of the element would also change. So my opinion is No.
What would happen if the sun was the only source of light?
It is the only source of light!
The characteristic of open source software?
only one? i would say no VIRUSES... :)
Is diode characteristic symmetrical?
Absolutely not. An ideal diode's characteristic would be perfect conduction in the forward direction and perfect insulation (no conduction) in the reverse direction. Silicon diodes come respectably close.
Why would it be hard to find the ideal light if the temperature were very hot or cold?
because if the light changed them so would the temperature
Why would it be hard to find ideal light intensity if the temperature were very hot or cold?
because if the light changed them so would the temperature
Why internal resistance of an ideal voltage source is zero and an ideal current source is infinty?
Current source means current generator for a circuit. An ideal current source gives all current to the circuit, but practically a current source does n't give all current to the circuit, instead, a source resistor is connected in parallel to the current source to indicate the current drop.
Why would it behard to find the ideal co2 level if the light intensity were very low?
because if the light change so would the temperature
Is there a need for a screwdriver with a light source?
I think that a screwdriver with a light source would be a marketable product. It would appeal to a wide range of professions. E.g. Joiners/carpenters.
How would you measure the brightness of light being produced by a source?
photometer or light meter
Would a light stick be a good light source in a potentially explosive environment?
Yes
What are 4 compents of a flash light?
Generically, a power source (usually batteries), a light source (usually a light bulb), a switch to turn it on and off, and wiring of some sort to connect the energy source to the light source. Theoretically this is the minimum you would need to build a "flashlight".
