When visible light hits the road some of it turns into heat (infrared) and the other gets reflected back as light.

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.
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 after the light is absorbed by a radiometer?
The light energy is absorbed and dispersed after it hits the radiometer.
Where do electromagnetic waves tranfer energy?
From one place to another. From the source of the radiation to whatever ultimately absorbs it. Example: Using your flashlight to see a rock on the ground at night. -- The energy begins as chemical energy inside the batteries in the flashlight. -- You switch the flashlight on. Electric current flows through the light bulb or LEDs. Most of the energy in the current changes to light energy and heat energy. The light energy pours out of the front of the flashlight. -- All of the air that the light passes through absorbs some of its energy. -- A lot of the light misses the rock, and hits the ground. The ground absorbs most of the energy in the light that hits it. Not much of the light energy that hits the ground bounces off of it. That's why the ground looks dark to you. -- Some of the light goes straight to the rock and hits it. The rock absorbs most of the energy in the light that hits it. Not much of the light energy that hits the rock bounces off of it. That's why the rock looks dark to you. -- Any light energy that hits the ground or the rock, bounces off of them, and hits your shirt, is absorbed by your shirt. -- Any light energy that hits the ground or the rock, bounces off of them, and happens to go through the dark circle in the middle of your eye, is absorbed in the cells on the back surface of your eye. That energy generates a little bit of chemical action, which generates a little bit of electric current, which flows through the optic nerve, to your brain, whereupon your brain generates the message "Hey! There's a rock right there, on the ground!"
What happens when heat 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.

When light hits an object most of the light is absorbed by what?
simple when a light strikes a surface the amount of energy that refactes that surface is generally aborbed by the object(material) which it aabsorbs the energy from light.
After light hits photosystem I its energy is used to produce what molecule?
NADPH
What energy transformation is it when sunlight shines on a tree?
The sun gives off light and thermal energy. When the light hits the leaves of the tree, the leaves undergo photosynthesis.
