It is not true.
A flashlight is an example of a series circuit; a battery in series with a switch in series with a bulb.
No, a dry cell used in a flashlight is an example of chemical energy, not mechanical energy. The chemical reactions in the battery produce electrical energy that powers the flashlight.
It's an example of a dry cell battery.
When light travels in homogenous mediums, like air in a room, it doesn't refract visibly to our eyes. Refraction occurs when light travels between mediums of different densities, such as from air to water or glass. In the case of a flashlight in a room, the change in density is minimal and therefore not perceivable as refraction.
Yes, a flashlight beam can be considered an example of a line segment, as it is a finite portion of a line that has a starting and ending point.
Neither. it is getting a flashlight wet. The beam of light from the flashlight will refract when exiting the tank (and refract several times if going through a glass wall of the tank). If the tank wall is smooth enough of a material with enough of a difference in optical density and the flashlight beam hits the wall at a small enough angle there will be total internal reflection.
An example of abrupt refraction is when light waves pass from air into water, causing a sudden change in their speed and direction. This can be observed when a straw seems to bend at the point where it enters a glass of water due to the refraction of light waves.
No,that is reflection. Refraction is when light travels through something clear like water or glass and then the lihght bends and maybe even makes a rainbow
" The light is bent by refraction, caused by the medium through which it passes"
Refraction is when they change direction slightly when entering the second medium, e.g. flashlight shining down towards water surface
This is an example of refraction of light. Refraction occurs when light passes between mediums of different densities, causing the light rays to change direction. In this case, the light bends as it passes from the air into the water, making the ruler appear bent or broken.
No, light bending through a prism is an example of refraction, not reflection. Refraction occurs when light passes through a medium with a different refractive index, causing the light to change direction. Reflection, on the other hand, occurs when light bounces off a surface.
