Capable of being refracted; able to change the direction of a ray of light or other form of radiation, when it passes obliquely from one medium into another of different density. This bending of light occurs because of a change in its speed. The degree of refraction depends on the angle of incidence and the difference in the refractive indices of the two media. The term applies not only to light but also to other electromagnetic waves, like radio waves, and even to sound waves under specific conditions. It is a key concept in optics and related fields, enabling the design of lenses, prisms, and other optical instruments.
Refractable meaning with examples
- The scientist meticulously polished the surface of the lens to ensure it was highly refractable. He needed maximum clarity for his experiment. Any imperfections would cause unwanted distortions in the light passing through it. Precise alignment and a flawless finish were crucial to the success of the project, allowing him to accurately observe and measure the refractable properties of the crystal being studied. The final results would depend on this element.
- The telescope's objective lens, made of carefully selected glass, was designed to be highly refractable. This property allowed it to gather distant starlight and bend it to a focal point. The quality of the images produced depended entirely on how well the light was refractable. Using different materials with varying refractive indices, it was able to correct for chromatic aberration, improving image quality and color accuracy. The design was complex and required the precise manipulation of light.
- The prism demonstrated a dramatic example of how refractable light could be separated into its constituent colors. When sunlight passed through the triangular glass, it dispersed into a beautiful spectrum. The amount by which each color bent depended on its wavelength, proving that light’s speed varied based on its color. This principle allows for the scientific study of light. The spectrum produced showcased the refractable qualities, allowing further investigation.
- Radio waves, though invisible, are also refractable, allowing them to bend around obstacles. This is how radio signals can sometimes reach beyond the line of sight. This phenomenon is impacted by the atmospheric layers. The ability to use refractable properties is how signals were able to travel long distances, and why certain bands and frequencies were preferred for certain geographical regions. This is essential for communication.
