A ray of light bends towards normal when it travels from denser to rarer because The speed of light increases The speed of light decreases The speed of light remains same None of these. A pencil appears bent when immersed in water because of refraction of light total internal reflection dispersion of light none of these. Which of the following is most important condition for viewing a rainbow? Sun should be between observer and water droplets in atmosphere. The observer should be between sun and water droplets in atmosphere. Water droplets should be between sun and observer. none of these. Mirage [illusion of appearance of water in desert in hot sunny day] occurs in deserts due to: refraction of light dispersion of light interference of light total internal reflection. Which gives both the conditions necessary for total internal reflection? Ray of light travels from rarer to denser and angle of incedense is more than critical Ray of light travels from denser to rarer and angle of incedense is less than critical Ray of light travels from denser to rarer and angle of incedense is more than critical Ray of light travels from denser to rarer and angle of incedense is less than critical.
