What are the four interactions light can have with matter?
The four interactions light can have with matter are absorption, reflection, transmission, and scattering. Absorption occurs when light is taken in by the material, reflection happens when light bounces off the surface, transmission is when light passes through the material, and scattering involves the redirection of light waves in different directions.
How does light interact with materials and what are the effects of this interaction?
Light interacts with materials in several ways, including absorption, reflection, transmission, and scattering. When light is absorbed by a material, it can cause the material to heat up or undergo a chemical reaction. Reflection occurs when light bounces off a material's surface, while transmission happens when light passes through a material. Scattering is when light is dispersed in different directions by the material. These interactions can affect the color, transparency, and overall appearance of the material.
What occurs when a wave strikes a boundary?
When a wave strikes a boundary, it can undergo reflection, transmission, or absorption. Reflection occurs when the wave bounces off the boundary and travels in the opposite direction. Transmission happens when the wave passes through the boundary and continues traveling in the same medium. Absorption occurs when the wave's energy is absorbed by the boundary material.
What does light rays bouncing off the surface of an object mean?
Scattering if it happens at random and said to be "reflection" if it is stream lined.
How absorption and scattering affect the beam of light?
Absorption occurs when a material takes in light energy, causing the beam to lose intensity as the energy is converted to other forms. Scattering happens when light is deflected in various directions by particles or surfaces in its path, reducing the overall intensity and sometimes causing the beam to spread out. Both absorption and scattering can alter the direction, intensity, and overall characteristics of a light beam.
Explain light attenuation in the water column?
Light attenuation in the water column is the process by which light decreases in intensity as it travels through water due to absorption, scattering, and reflection by particles and dissolved substances. Absorption occurs when light is absorbed by water molecules, particles, and dissolved organic matter. Scattering happens when light is redirected in different directions by particles and molecules in the water. Reflection occurs when some light is bounced back from the water surface. Together, these processes result in reduced light penetration with increasing depth in the water column.
How do absorption and reflection relate to one another in the context of light and sound waves?
Absorption and reflection are two ways in which light and sound waves interact with surfaces. Absorption occurs when waves are taken in by a material, converting their energy into heat. Reflection, on the other hand, happens when waves bounce off a surface without being absorbed. In the context of light and sound waves, absorption and reflection are related in that they both affect how waves behave when they encounter different materials or surfaces.
What is the difference between absorption loss and scattering loss?
absorption: having a change in energy from source to the receiver by its medium scattering by particles: occurs without a change in energy, but results in a change in direction of propagation
What happens to a wave when it reaches a boundry?
When a wave reaches a boundary, it can undergo three main phenomena: reflection (bouncing back), transmission (passing through), and absorption (being absorbed by the boundary). The specific outcome depends on the properties of the boundary and the characteristics of the wave.
Describe the behavior of waves when they strike a surface?
laws of reflection
How does reflection and absorption play a role in your ability to see?
Reflection occurs when light bounces off an object and into your eyes, allowing you to see the object. Absorption happens when light is absorbed by an object, preventing it from reaching your eyes. Both processes are important for how we perceive and see objects in the environment.
What happens as light travels farther from its source?
As light travels farther from its source, it spreads out and disperses, causing its intensity to decrease. This is known as light attenuation. Additionally, light may interact with particles or obstacles in its path, leading to absorption, reflection, or scattering, further reducing its brightness.
