- C.
Two-Legged Animal With Feathers And Wings
- D.
Weather Radar That Measures Direction And Speed Of A Moving Object
Correct Answer
A. Scattering Of An Electromagnetic Wave As LightExplanation
Dispersion refers to the phenomenon of scattering of an electromagnetic wave as light. When light passes through a medium, such as a prism, it gets separated into its constituent colors due to the varying refractive indices of different wavelengths. This scattering of light is known as dispersion. It is responsible for the formation of rainbows, as well as the colorful patterns observed when white light passes through a prism.Rate this question:

- D.
Orbit Which Describes An Ellipse Or Oval Shape
Correct Answer
D. Orbit Which Describes An Ellipse Or Oval ShapeExplanation
An elliptical orbit is a type of orbit that describes an ellipse or oval shape. In astronomy, it refers to the path that a celestial object, such as a planet or satellite, follows around another object under the influence of gravity. Unlike a circular orbit, an elliptical orbit is elongated and has varying distances between the two foci of the ellipse. This means that the object's distance from the center of the orbit and its speed will change as it moves along the ellipse.Rate this question:
