When a light ray beam goes from one material into another, but with a higher refractive index, you know that its speed and wavelengthbut its frequency will 6. If the a ray of light strikes a boundary between two transparent materials, and there is no transmitted ray, circle only one option(T F)to evaluate if it is correct to conclude that the indices of refraction of these two materials is the same. of with wavelength is known as 7. The slight variation of 8. A paraxial ray is 9. The rainbows are caused because of the following phenomena: 10. The top color in the rainbow is while the color is because 1/4

Explanation / Answer

4.

the angle in region of "n2" is larger as compared to the angle in region of "n1". we know that the ray bends towards the normal in denser medium. hence n1 region is denser.

so index of refraction of n1 > index of refraction n2

5.

decreases.

but frequency remains same,

6.

False
