Lecture Notes: https://drive.google.com/file/d/1dw70... Question 1 A ray is incident on a plane mirror. It's reflected ray is perpendicular to the incident ray. Find the angle of incidence Question 2 A man standing in front of a plane mirror finds his image at a distance 6 metre from himself. What is the distance of a man from the mirror? Question 3 An insect is sitting in front of a plane mirror at a distance 1 m from it. (a) Where is the image of the insect formed? (b) What is the distance between the insect and it's image? Question 4 An object is kept at 60 cm in front of a plane mirror. If the mirror is now moved 25 cm away from the object, how does the image shift from it's previous position ? Question 5 An optician while testing the eyes of a patient keeps a chart of letters 3 m behind the patient and asks him to see the letters on the image of chart formed in a plane mirror kept at distance 2 m in front of him. At what distance is the chart seen by the patient? #icse #cbse #science #physics #numericals #icseclass9 #cbseclass9 #light #reflection #reflectionoflight
