What is the difference between lamp and torch?
a lamp uses electricity and a light bulb, a torch is fire
Is torch light a source of light?
yes
What happens if a torch is shone at 90 degrees under water. would it refract?
If the torch light is fully underwater it could be held at any angle between 180 degrees before it refracted, as refraction involves light passing between two media with different densities. If water is constantly the same density it will not bend the light.
What is the purpose of the concave mirror behind the bulb in the flashlight?
You want a torch to emit light in a beam, in only one direction. But the bulb in the torch emits light in all directions, the mirror reflects the light going in the wrong direction(towards the inside of the torch) back out the front of the torch making it brighter. It is concave so as to focus the light more.
Is battry life is less if torch light passing through water?
The medium through which the emitted light of a torch passes will not affect the battery life of the torch. The battery life of the torch will be the same if you are shining it through air, glass, water, or anything else.
Why laser torch light is more than general torch light?
There is not more brightness for laser torch light. The light brightness is based on unit lumens. Lumens is more, the touch light is more lighter.

What is the difference between a torch and a flashlight?
There is no difference. Flashlight is the American word for what the English speaking countries call a Torch. This then avoids confusion when using a camera with a flash!
What is the role of a dry cell in a torch?
To provide the electric potential difference required to get a current flowing through the bulb and the torch to produce light.
What is the difference between electrical and torch soldering?
When soldering a person can use an electric tool or a torch. The torch uses a flame, while an electrical tool has a soldering tip which is heated.
What is difference between rim blackberry torch 9800 - charcoal and rim blackberry torch 9800?

Why do you light the Olympic torch?
A torch is carried to help people see in the dark of night.
What happens when you use a flashlight in outer space?
The currents flow through the torch and we get light from the torch
How does a torch switch work?
It provides the light in the torch
Who lights the torch and who did they decide would light the torch?
god
What is an Ultraviolet torch?
a torch that emits ultra-violet light
Would light weaken the further away it was from its source?
No light is composed of massless particles called "photons", the reason some lights such as torches, seem to weaken the further they get from the torch, is because the light from a torch is not as focused as the light from a laser beam, the photons that make up the light, simply spread out over greater distances. Photons themselves do not weaken, they will travel until they reach an object they cannot pass through.
