Burning Science Questions? Ask Pang

Do you have any science query which keep lingering in your mind that you want to get an answer or explanation to it in order to satisfy your curiosity? Or if you are a student and have some questions relating to science and maths from your studies? If your answer is yes, then time for you to clear your doubts in science and maths. Just email me.

Please note that the answers will usually be sent to you via email. However, if you ask a question or I encounter one which is considered challenging and usually appears in examinations and tests, then I will post it under Question of the Week and open to the public, before I upload the answer(s) here. You maybe a winner for answering the question**. Kindly refer below for more information.

Question of The Week

This question consists of 2 parts, secondary standard. This is a common O’level question under the chapter on Light. Students are encouraged to learn to be able to answer this question. Though common, many students are not able to answer it correctly. The thickness of the mirror is another confusing one.

Part I: Two mirrors are placed perpendicularly at each other as shown with their reflective sides facing inwards. A point object O in front of both of their reflective sides. Imagine you try to look for images of the object formed by the two mirrors by placing the position of your eye as shown.

Draw light rays (virtual and real) showing how you will be able to see the images.

Part II: How many images are actually formed?

Feel free to answer this question and email me your answers (for both parts) if you agree to the below terms and conditions. You can also write your answers on a piece of paper, scanned it and send to me the image file. In your email, please also include your name, school and level, otherwise, your entry will be rejected. The first two participants who email me with the correct or best (may not be completely correct) answers will be the Winners (will be notified by email). Each will receive a surprise gift (worth about $15) and a $20 dollar voucher to offset fees for small group tuition in our Centre. Deadline is 15 Jan 2009. Winners’ names, school and their original unedited answers will also be posted here. Kindly note that, I will write comments on any answers and explanations from the winners posted here, on the basis of O/A’level examinations requirements and scientific concepts. This is to enable the rest of the students to learn as well.
