What would happen if a light source was lite in a mirrored sphere?
Arch Teryx asked:
I’ve wondered about this before. It’s purely hypothetical and some variables must have restraints placed on them eg. the light source can’t absorb any energy nor can it impead the reflection. Second one has the ability to look in without light escaping.

That said if a white light went off inside a mirrored sphere what would be the resulting effect. There would be infinite recursion from a infinite number of angles. Would interferance of various wavelengths cause a color shift or would there be a centralized ball of light.

cragoogle asked:
We see light energy waves with our eyes, and hear sound energy waves with our ears.
We see light energy waves with our eyes, and hear sound energy waves with our ears.
Light can be broken down into different wavelengths meaning we see different colours and can also be broken down into ultra violet and infra red; sound can be different wavelengths making different sounds and pitches.
They are both energy waves.
Are they the same energy broken down into different wavelengths resulting in us seeing that energy as light and sound?

light?
Rec asked:
when light enters a prism, does the sphape of the prism effect the direction light changes????
when light enters a prism, does the sphape of the prism effect the direction light changes????
for example: light enters a glass that has a rectangular prism shape or light enters a glass that has a cone shape.
i also have that same thought because i was about thinking about the shape of a diamond. Too deep or too shallow will cause light to be not refracted as much.

What are the light intensities of each wavelength of sunlight?
jamie e asked:
I, like many others at the moment, have been set a peice of work to plan an investigation into how light intensity of a bulb emmitting similar light to sunlight (specialist bulb for growing plants) changes at its different wavelengths. I would very much appreciate it if someone could find for me a table or graph with a number of wavelengths in nm, and their corresponding intensities in kW/m2/s or similar, for sunlight. Also, if anyone has any more general tips for how to conduct the experiment, I would be very pleased to hear them. My plan so far is simply to use filters to get light of a specific wavelengths and then use a multimeter to measure the resistance of an LDR near to the light, as an indication of light intensity of that wavelength. Most important thing though, is to get a table/graph of some preknown values. Thanks very much.

What happens to all the light energy when you turn off a light switch?
Steven B asked:
How is it that an entire room can be illuminated by one small light source, yet when that source is stopped, every trace of light is gone?
How is it that an entire room can be illuminated by one small light source, yet when that source is stopped, every trace of light is gone?
Is it just instantly absorbed by the surrounding surfaces?
I would think there might be a brief moment where the residual light is reflected back and forth between the walls or something.
Would the effect be the same in a room with a completely reflective floor, ceiling, and walls? Or would the light energy bounce continuously off the walls, keeping the room illuminated even in the absence of continuous source of light?
I’m sure there is a simple explanation, but please, enlighten me.

varghese p asked:
I understand that as the light intensity increases the resistance decreases and vice versa in an LDR. But I don’t know why, shouldn’t it be the other way around because in the morning when there is high light intensity shouldn’t it there be high resistance to prevent any current to light up the bulb. And at night when there is low light intensity the resistance decreases to allow more current to light up the bulb. Thanks!

What are the main advantages and disadvantages of different lighting for reading?
Gene K asked:
I was wondering if there’s any particular lighting that is better for illumination, eye strain, headaches, color of light, etc. Do some lighting sources flicker, causing eye strain? I’m wondering about incandescent, compact fluorescent, and LEDs, natural light, and candlelight. Seems natural light would be the best… however I do sometimes find it difficult to read outside on a really bright day, so maybe not. I also see an advertisement for Tensor brand full spectrum light, but I don’t know what kind of bulb that has.

What causes gradual lighting up of street illumination on long streets?
mr_fish04 asked:
When they light up street illumination in cities like New York, it seems to be progressive and not all the lights are on at the same time. It seems like a “flow of power” turning them on gradually as it progresses through the wires. But I am quite convinced that it is just for effect or rather to protect the power network and not because electric current works like that. I think that physicaly when you connect power supply to a wire all the lights connected to that wire light up at the same time no matter how long the wire is. Is there any related material online describing this problematics of lighting up big cities?
