A very smooth, distempered wall reflects the light falling on it, Why doesn’t a person standing in front of it, sees his or her image in it? A transparent object/ material allow the light falling on it, to pass through it. How does it make itself visible? What happens when a ray of light is incident normally on the surface of a plane mirror? The ray of light falling on a rough surface follow the laws of reflection and yet no image in obtained due to reflection from a rough surface. Justify the phenomenon. What will happen if the light sensitive cells or photoreceptors are completely missing from the retina of a person’s eye? The normal rate of flashing the till pictures in front of human eyes to project a movie film at normal speed is 24 stills per second. T o show a slow motion film, the rate of flashing stills should be more than or less than 16 stills per second? Give reason for your answer. Causing of presbyopia, a defect of eye? The Moon is seen in different shapes every night throughout a month. The life of the Sun will come to an end after roughly 5, 00,000 years from now. Why are stars visible only at night   Why is Pluto not considered a planet of our solar system after August 2006 Why does the tail of a comet always point away from the SUN? How do meteorites help in getting information about space?

(3 X 3 = 9) CASE STUDY QUESTION 26. Ultrasounds can be used to detect cracks and flaws in metal blocks. Metallic components that are generally used in construction of big structures like buildings, machines and also scientific equipment. The cracks or holes inside metal blocks, which are invisible from outside, reduce the strength of the structure. Ultrasonic waves are allowed to pass through the metal block and detectors are used to detect the transmitted waves. If there is even a small defect, the ultrasound gets reflected back indicating the presence of flaw or defect. Clearly indicated in the figure Defect or flaw Ultrasound Detectors Metal Block (a) The transmitter sends an ultrasound wave of speed 5960m/s through a long steel bridge and a block reflects it back after 0.02s. how far the block in the metal bridge is from the transmitter. (b) With the above property of ultrasound waves, Can ultrasonic waves be used in the medical field? If so, how and give one use in the medical field to justify your answer? (c) Give two practical applications of reflection of sound waves?
