How does the energy change in a chemical reaction?
Sideways, according to Newton. No gain, no loss. No hits and no fouls. Thermal begats light. Light gives heat. Heat gives energy. That gives light. That grows food. Round and round. There is no change, only conversion.
Is light mechanical energy?
Light is not mechanical energy but it can be transformed into mechanical energy. Light creates an impact as it hits a surface.
Energy carried by light?
Light carries energy in the form of electromagnetic radiation. This energy is quantized into discrete packets called photons. The energy of each photon is determined by the frequency of the light, with higher frequencies corresponding to higher energy photons.
Can light go through water?
The light will change directions (to be closer to the normal) once it hits the water. This is known as refraction which is a property of light. In this case, you have 2 media (plural form of medium). The two are air and water.The reason it changes direction is because air allows a different speed of light than water. Water is denser which is why light can't travel as fast. This change in the speed of light is what causes the light to change direction once it hits the water.In conclusion, after light hits the water, it will change directions (to be closer to the normal) due to the fact that the medium is changed (from air to water) which results in a change in the speed of light.
Why does light change direction when it hits things?
Light changes direction when it hits a shiny surface
What happens when light passes into water?

What materials absorb light and how do they do so?
Materials that absorb light typically contain pigments or dyes that are able to absorb certain wavelengths of light. When light hits these materials, the pigments or dyes absorb the light energy, causing the material to appear darker or change color. This absorption of light energy is what allows these materials to absorb light.
What happens when light hits metal?
When light hits metal, the atoms in the metal absorb the energy from the light. This causes the electrons in the metal to become excited and jump to higher energy levels. The electrons may then re-emit the absorbed energy as light if they return to their original energy levels, a phenomenon known as reflection.
What happens when hits a solid?
The same with when a light hits a solid; the energy either gets reflected or absorbed. If light hits a dark colored solid, most of the light will be absorbed, and the black object will get warm.If light hits a light-colored solid, most of the light will be reflected, and the white object will stay cool.By the way, the same thing happens to both heat and light, because heat is a form of light; heat is also called infrared light.Further answerIt does depend somewhat on what form this heat is in. If it's radiation then the answer above is fine. But if it's in the form of say, hot air, then there won't be any reflection, just conduction of the heat from the air to the solid.
What happens when light hits a flower?
When light hits a flower, the pigments in the flower's petals absorb the light energy. This energy is then used in the process of photosynthesis to produce sugars that the plant uses as a source of energy to grow and bloom. The color of the flower is determined by the specific pigments present in its petals and how they interact with light.
When light hits an object some of the light is absorbed by what?
When light hits an object, some of the light is absorbed by the electrons in the material. The absorbed energy can cause the electrons to move to a higher energy state, leading to absorption of specific wavelengths of light depending on the material's properties.
What happens to light when it hits a opaque object?
When light hits an opaque object, it is absorbed by the object's surface material, leading to a conversion of light energy into thermal energy. The opaque object does not transmit or reflect the light, causing the object to appear solid and non-translucent.
