How can light be used to make food? When a person turns on a lamp, electrical energy becomes light energy. Like all other forms of kinetic energy, light can travel, change form, and be harnessed to do work. In the case of photosynthesis, light energy is converted into chemical energy, which photoautotrophs use to build carbohydrate molecules. However, autotrophs only use a few specific components of sunlight.
What determines the colors seen when light exits a raindrop? - Answers
Light is made up of many different colors, all of which have a different wavelength. Normally when we see light from the sun it appears colorless. So how is it that colorless light gives us colors? What makes a rainbow?
What Is the Visible Light Spectrum?
Asked by Wiki User. White light is a mix of different colors. Different colors will be refracted at different angles, so they will exit a raindrop in different places. A beam of light is made up of all seven colors, the color we see on an object is the color the object reflected.
When the flashlight is in the air and the refracted ray enters the water, how does the angle of refraction compare with the angle of incidence? The angle of refraction is smaller than the angle of incidence, other than when the flashlight is on the normal line. When the flashlight is in the air and the refracted ray is in the water, what happens to the angle of refraction if you increase the angle of incidence? The angle of refraction increases.
