What else can I help you with?
An ideal Polaroid will transmit 50 percent of nonpolarized light incident on it How much light is transmitted by two ideal Polaroids that are oriented with their axes parallel to each other?
When two ideal polaroids are oriented with their axes parallel, the total amount of light transmitted would be 50% of the light transmitted by the first polaroid, which is 50%. Therefore, the total light transmitted through both polaroids would be 25%.
What will happen to the shadow if a stronger light source is used?
The shadow will typically become darker and more defined when a stronger light source is used. This is because the stronger light source will create more contrast between the object blocking the light and the surface where the shadow is cast.
Could you emit the same amount of light energy per second which must emit more photons per second a source of red light or a source of blue light?
A source of blue light would need to emit more photons per second to produce the same amount of energy as a source of red light. This is because blue light has higher energy photons, so fewer photons are needed to achieve the same total energy output as red light, which has lower energy photons.
What will happen if light did not exist?
Without light, there would be no visibility, as vision is dependent on light for perception. Plants would not be able to photosynthesize, leading to a loss of the primary source of energy for many organisms. The absence of light would also disrupt various ecosystems and natural processes that rely on light for survival.
Why don't flames have shadows and how does this unique characteristic contribute to their appearance and behavior?
Flames do not have shadows because they are a source of light themselves. The light emitted by flames is so bright that it overpowers any shadows that would be cast. This unique characteristic contributes to the appearance and behavior of flames by making them appear vibrant and dynamic, as they seem to dance and flicker without being constrained by shadows. Additionally, the lack of shadows allows flames to illuminate their surroundings more effectively, creating a mesmerizing and captivating display.
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... :)
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
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 ideal light intensity if the temperature were very hot or cold?
because if the light changed them 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.
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.
What is the height of the shadow when the distance from the light source to object is 24cm?
It depends what angle the light is at, for example the shadow would be longer if the light was looking atr the object from the side (45 degrees) than it would be if looking at it from the top of the object(180 degrees).
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".
What is the basic source of light?
On our planet it would be, Sol, our sun.
What reference source would you use to find the synonym to angry?
Wiki Answers, a dictionary, or a thesaurus. (thess OH russ)
