- Absorption: The object absorbs some or all of the radiation, which can lead to heating or ionization.
- Reflection: The radiation bounces off the object without being absorbed, similar to how light reflects off a mirror.
- Transmission: The radiation passes through the object without being absorbed, like how X-rays pass through the body during a medical imaging procedure.

What are the four main things that can happen when light hits an object?
When light hits an object, it can be absorbed (taken in by the object), reflected (bounced off the object), transmitted (pass through the object), or refracted (bent as it passes through the object).
What is radiation in simple terms?
Radiation is energy that travels in the form of waves or particles. It can come from natural sources like the sun or man-made sources like X-rays. When radiation hits an object, it can transfer energy and potentially cause changes to the object's atoms or molecules.
What happened when infrared radiation hits something?
When infrared radiation hits something, it can be absorbed, reflected, or transmitted through the material. The object will absorb some of the radiation, causing it to increase in temperature. The amount of absorption depends on the material's properties and can be used for various applications such as thermal imaging and remote temperature sensing.
How thermal energy is transferred by radiation?
Radiation is the transfer of energy by electromagnetic waves. Considering the dual nature of electromagnetic radiation, you could also consider it to be transferred by photons of the electromagnetic radiation. The rate of transfer of radiation is given by the surface area of the radiation source, the surface area of the object receiving the radiation, a geometric coefficient accounting for how much of the radiation from the source actually hits the receiving object, a physical constant called the Stephan-Boltzman constant, the reflectivity, transparency, and absorbtivity of the receiving object for the wavelengths of the radiated energy, and the difference in the 4th power of the thermodynamic temperatures of the objects.
Where does the light come form?
Light can come from various sources, such as the sun, light bulbs, candles, or fires. It is created by the emission of electromagnetic radiation in the visible spectrum. When light hits an object, it can be absorbed, reflected, or transmitted, which is how we see things around us.

What 4 things happen to light when it hits an object?
it can be transmitted, reflected, refracted or diffused. In most cases, some combination of these occurs.

What are four possible things that can happen when light travels in a straight path until it hits an object?
Reflection: Light bounces off the surface of the object. Absorption: Light energy is absorbed by the object. Transmission: Light passes through the object without being absorbed or reflected. Refraction: Light changes direction as it passes through the object, due to a change in the medium's optical density.
What component of sunlight is responsible for heat?
Infrared radiation is the component of sunlight responsible for heat. When sunlight hits an object, the object absorbs some of this infrared radiation, which causes its temperature to rise and gives us the sensation of warmth.
What three things can happen to a light wave when it strikes an object?
A light wave can be absorbed by the object, reflected off the object, or transmitted through the object depending on the material properties and the angle of incidence.
When a ray of light hits a surface two things will happen to the light. What are they?
When a ray of light hits a surface, two things can happen: reflection, where the light bounces back off the surface, and refraction, where the light enters the material and changes direction.
What will happen when a dynamic object hits a static object?
When a dynamic object hits a static object, the dynamic object will typically experience a change in its motion and may transfer momentum or kinetic energy to the static object. Depending on the properties of the objects and the force of the impact, the dynamic object might bounce off, come to a stop, or cause the static object to move.
Why does an object appear to be black in color?
An object appears black when it absorbs most of the visible light that hits it, reflecting very little light back to our eyes. This lack of reflected light gives the object a dark appearance, making it appear black in color.
