Autotrophs that utilize light as their energy source are called phototrophs. These organisms are able to perform photosynthesis to convert light energy into chemical energy for their survival and growth. Examples include plants, algae, and some bacteria.
No, light is not a source of energy at all. Light is something we make with energy. We use water, wind, solar power, coal, natural gas or oil to create electricity which we use to make light.
No, flashlights do not use electromagnetic waves to create light. Instead, they use electrical energy to power a light source, such as a bulb or LED, which emits visible light when energized. Electromagnetic waves are a form of energy that can transmit light, but they are not the source of light production in a flashlight.

The source of light used in a diffraction grating is typically a monochromatic and collimated light source, such as a laser. This type of light source emits a single wavelength of light in a narrow, parallel beam which is important for producing sharp and distinct diffraction patterns.
IF YOU HAVE A MICROSCOPE THAT DOES NOT HAVE AN INTERNAL LIGHT SOURCE, YOU WILL HAVE TO USE THE EXTERNAL LIGHT SOURCE THAT IS PROVIDED IN THE CABINET WITH THE MICROSCOPE.
Plants, and some algae.
A small, portable light source.
Mitochondria do not use light.Mitochondria use chemical energy.
You can use either a pre-built in app or you can easily download a flashlight app from the app store or Google play store and use that as a sufficient light source.
Candles have been a primary light source historically due to their portability, ease of use, and accessibility of materials for their production. Additionally, candles provide a warm and natural-looking light that can create a cozy atmosphere in a variety of settings.
To see the source of light, you can follow the direction in which the light is coming from. This could be by observing the origin of the light beam or tracing it back to its starting point. Additionally, you can use tools like mirrors or lenses to redirect and focus the light to pinpoint its source.
