Answer:
1.D
2.B
3.D
4.C
5.C
Explanation:
1.D.The higher the wavelength,the lesser the refractive index.
2.B.What happens to the light particles when light hits an uneven surface? They are reflected off in a straight line. They are scattered in many directions.
3.D.violet light
The light waves are refracted as they enter and leave the prism. The shorter the wavelength of the light, the more it is refracted. As a result, red light is refracted the least and violet light is refracted the most - causing the coloured light to spread out to form a spectrum. This is called dispersion.
4.C. VIOLET
Violet has the highest frequency and the shortest wavelength.
5.C.
Visible light composed of 7 colors
•the 7 color that make up visible lights are:
-red,orange,yellow,blue,green,indigo,violet
(ROYGBIV)
•they go from longest wavelength and shortest wavelength.
