Does this colour correspond to th... 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh Draw a neat and labelled diagram of the experimental set up for observing the scattering of light in a colloidal solution of sulphur to show how the sky appears blue, and the sun appears red at sunrise and sunset. 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh Why are the ‘danger signal’ lights red in colour? 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh Why does the sun appear red at sunset? 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh Why does the sun appear red at sunrise? 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh Why does the sky appear dark (or black) to an astronaut instead of blue? 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh Why does the sky appear blue on a clear day? 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh What happens when a beam of sunlight enters a dusty room through a window? Explain your answer. 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh What is Tyndall effect? Explain with an example. 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh State two effects produced by the scattering of light by the atmosphere. 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh Which effect is illustrated by the observation that when a beam of sunlight enters a dusty room, then its path becomes visible to us? 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh What colour does the sky appear to an astronaut? 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh The scattering away of red light makes the sky appear blue during the day time. (b) The scattering away of blue light makes the sun appear red at sunset. 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh Which of the two is scattered more easily light of shorter wavelengths of light of longer wavelengths? 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh What is the colour of the sunlight : (a) scattered by the dust particles in the atmosphere? (b) scattered by the air molecules in the atmosphere? 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh A student claims that because of atmospheric refraction, the sun can be seen after it has set, and the day is, therefore, longer than if the earth had no atmosphere. 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh By how much time the day would have been shorter if the earth had no atmosphere? 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh We know that light refracts (or bends) when it goes from one medium to another. Now, the atmosphere contains only air. Then how does light get refracted on passing through only air in the atmosphere? 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh What is atmospheric refraction? What causes atmospheric refraction? (b) Why do stars twinkle on a clear night? (c) Explain why, the planets do not twinkle at night. 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh Explain why, if we look at objects through the hot air over a fire, the objects appear to be moving (or shaking) slightly. 3 years ago Deepak Rock class 10 the human eyes colourful world lakhmir singh Page 2 / 5 Prev 1 2 3 4 5 Next Share: Super Globals Requests: Server: Options and Features route: community use_home_url: url: https://eanshub.com/community/ pageid:187 default_groupid: 3 2022 How Can We Help?
