A light bulb or LED (light emitting diode) is commonly used in headlights and flashlights to produce a beam of light. The light source is powered by a battery or electrical circuit to emit light. Reflectors or lenses are often used to focus and shape the light into a beam.

If you were travelling at the speed of light and turned on a torch in your spaceship would you see a beam of light from the torch?

You can't travel at the speed of light. Accelerating a finite mass to lightspeed requires an infinite amount of energy.If you were traveling at nearly the speed of light, relativity says the beam of light from the torch would appear to you to be traveling just as fast as it would if you were standing still.Uh, it's a bit academic, but in reality there's nothing that says a mass can't travel faster than light. While it's true that a mass can't be accelerated to the speed of light from any lesser velocity, it doesn't rule out masses that might always have had a velocity greater than the speed of light.


How concave mirror is used in head lights and search lights throw light at long distances?

A concave mirror is used in headlights and searchlights as it can reflect and focus light beams to a single point, creating a strong and concentrated beam that can travel long distances. The mirror's shape allows it to gather light from a wide area and direct it in a specific direction, increasing the reach and intensity of the light projection.


Do matches light because of friction?

yes, the red part of the match on the end of the stick along with the red piece on the side of the box have tiny spikes which, when rubbed, create friction. The friction causes heat, which ignites the tip of the match.
