What do star twinkle |
| Answer» Becoz of the atmospheric refraction...... as stars are far away from earth they appear as the point source of light...... when the path of rays of light coming from the star goes on varying slightly, the Apparent position of the star fluctuates and the amount of star light entering the eye flickers-the star sometimes appears brighter, and at sometime fainter,which is the twinkling effect............. | |
