yes, a straight line

because the light is shorter
A beam is a general term, a ray is a vector having both direction and angular displacement.
When a beam of light passes through a colloidal solution it scatters because of tyndall effect.
Neither. The beams of red light and green light will have the same number of Photons, as energy is only related to frequency. The number of Photons is dependent on the intensity of the light beams.
a cone that does not have a tip
A flashlight beam is like a acute
a ray
probably a cylinder
A flash or beam of light
It is a ray [of coherent light], a physical term.
The beam of a flashlight (also known as a torch) is the cone where the light shines. A camera flash is a device that emits a brief intense pulse of light which can help to take a picture, particularly in poor light.
There is no standard collective noun for the noun 'light'. However, collective nouns are an informal part of language. Any noun that suits the situation can function as a collective noun; for example, a ray of light, a beam of light, a glare of light, etc.
Ray
A cone.
Laser light is made of just one type of wavelength vs multiple types in regular light. The waves are all in step with each other or coherent. Laser light is made when energy is fed into a liquid, gas, or solid. The energy is absorbed into atoms and light of one wavelength is the result. The light from the atom hits other atoms and a chain reaction begins. Many of the atoms will begin releasing light and hits a mirror inside the laser. They will bounce around inside getting more and more intense until a beam is produced.
