Final answer:
Transparent materials are what allow light to pass through in straight lines, enabling us to clearly see objects on the other side.
They are distinct from opaque and translucent materials, and are an important concept in geometric optics where light is considered to travel in rays.
The Correct Option is; Transparent materials
Step-by-step explanation:
Materials that allow light to pass through them in straight lines are called transparent materials. When light interacts with materials, it can be reflected, absorbed, or transmitted.
Transparent materials, such as clear glass or some types of plastic, permit the transmission of light without significant scattering, so objects on the other side can be clearly seen.
This contrasts with opaque materials, which do not allow light to pass through, and translucent materials, which allow light to pass but scatter it, causing objects behind to appear blurred.
In geometric optics, light is conceptualized as traveling in straight lines called rays. Light may change direction upon encountering an object or when passing from one material to another due to reflection or refraction, but within a single medium, it travels in straight lines.
, the ray model of light is key in explaining how we see objects through transparent materials.
Materials that allow light to pass through them in straight lines are called transparent materials. Transparency refers to the property of a material that allows light to transmit through it without scattering or absorbing the light.
Examples of transparent materials include glass, water, and clear plastic.
