Sahil, Rekha, Patrick, and Qasima are trying to observe the candle flame through the pipe as shown in Fig. 11.16. Class 7

Sahil, Rekha, Patrick, and Qasima are trying to observe the candle flame through the pipe as shown in Fig. 11.16. Who can see the flame? Class 7

Answer:

Rekha can see the flame through the pipe, because the light from the flame travels in a straight line. Since the pipe for all others are bent (not straight), therefore they will not see the flame.
