NCERT Solutions for Class 12 Physics

He felt that he could buy new balls, and those would create new memories or moments for him, but those that were gone with the ball into the water would never ever return. He realised that those moments would never come back, just as the ball. Why doesn’t he offer him money to buy another ball? Why does the poet say, “I would not intrude on him”? Some of the lines that appear funny in the poem are “A noble wild beast greets you”. For example in the poem ‘Tale of Custard the Dragon’ by Ogden Nash, the spellings have been changed to create a rhythmic effect – realio, trulio instead of really and truly. This is often referred to as ‘poetic license’.
Fog is a visible aerosol consisting of tiny water droplets or ice crystals that remain near the surface of the earth. Therefore, when white light enters a prism, it disperses into seven constituent colours, and violet light shows the maximum deviation. The refractive index of the medium is maximum for violet light and minimum for red light. Hence, in this case, the Sun will be in the east direction.
Use this table to quickly look up any height in centimeters and find the equivalent in feet and inches plus total inches. To convert cm to feet, divide the centimeter value by 2.54 to get total inches, then split that into feet and remaining inches. Drag the slider to visualize how centimeters translate to feet and inches in real-time. Enter Adda in centimeters and instantly see the result in feet and inches.

(b) If white light is used in the same way as in part (a) above, what change is expected in the emergent beam? (a) After dispersion through the prism, constituent colours of white light are seen on the screen. The diagram shown below shows the path taken by a narrow beam of yellow monochromatic light passing through an equiangular glass prism. (c)Which of the colour of the spectrum of white light deviates (i) the most? On which surface of the prism, there is both the dispersion and deviation of light, and on which surface of the prism, there is only the deviation of light?
Write the seven prominent colours present in white light in the order of increasing wavelength (b) The wavelengths of violet and red light are 4000 respectively. (a) Write the approximate wavelengths for (i) blue and (ii) red light. What is the range of wavelength of the spectrum of white light in (i) and (ii) nm?
(a) For blue light, approximate wavelength is 4800and for red light, approximate wavelength is 8000 Due to this phenomenon, some light rays get absorbed while a few get scattered in various directions. Light (visible light) is a type of electromagnetic radiation within the section of the electromagnetic spectrum observed by the human eye. Molecules with a larger size than the wavelength of light experience the scattering effect differently; the phenomenon is known as the Mie effect. However, the power of his wish made him fly the plane into the storm. In this humorous poem, the poet Carolyn Wells suggests some useful ways to identify wild animals while in a jungle. In this chapter, Class 10 students will learn about a mysterious story revolving around a pilot.
Students can find insights about the poetic devices and imagery that are used to express the major themes of struggle and obstacles faced by man and animal. Hence, with the aid of the other pilot, he landed safely on the runway. He blindly followed the other pilot as the radio signals were dead and he had almost run out of fuel. The pilot waved his hands and asked him to follow. The narrator of the story, flying a plane to his homeland, hoped to be with his family and have a good breakfast with them. His mother guided him, and soon, he realized that he was flying in the open air. It worked as the little seagull was very hungry, and he soon dived for that bait.
The poet suggests that if a large and tawny beast roams in the jungle in the east and roars towards us, then it is the Asian Lion. How does the poet suggest that you identify the lion and the tiger? If we pronounce the word ‘lion’ as ‘lying’, then probably it would rhyme with the word ‘dyin’. Have you ever been alone or away from home during a thunderstorm? Tick the words which have the same or nearly the same meaning.
