the question is phrased poorly, but i think the answer is seven, as in white light is split into seven different wavelengths when passed through a prism.
A beam of light is made of photons, which are massless particles that carry electromagnetic energy. When a light source emits photons, they travel in waves at the speed of light, illuminating their surroundings.
More than 1. Describing the intensity of the beam will establish the number of photons per second striek a perpendicular surface of a given area.
It does depend on the kind of laser, but the main difference is that a laser emits a focused beam of light of the same wavelength (i.e. color) while a flashlight emits light of many different wavelengths, and 'beams' this light by reflecting it using a concave mirror built into it behind/around the bulb.
A laser, by its very action of amplification of light, tends to be monochromatic. (one colour). But lasers may be made in several different colours depending on the materials used.
A laser beam typically consists of light with one frequency (or color) corresponding to a single wavelength. Energy levels in a laser beam depend on the material and process used to generate the laser light, often resulting in coherent and high-intensity light output.

On a four headlight system there are two filaments for the inner lights. They have a filament for a high beam and one for a low beam.
fairy lights aremade out of many small lights. the lights are like the lights you put on a Christmas tree, but smaller. they are filled with gasses used in go green light bulbs.

100 metres?
Yes, if they are the same type of lights, having twice as many lumens gives you twice as much light, regardless of how many lights you need.
there are only one type of LED lights. a bunch of LED lights is Three light.
On an average car, there are high and low beam lights for night driving, clearance lights on the front and back, front and rear turn signals, and back-up lights used when backing up.
Up to 3,000 lights
