[S3 Physics PMCians]
What we did in 2 hours:
On 6th, 8th and 9th Aug, the S3 PH has come together to complete the following:
1) Secret Enclosed – Light Part I (Reflection and Refraction)
2) The Final Lap – Light Waves 1
Two things to remember:
- For reflection: The three steps to drawing how the eye perceive the object through the mirror is the usual procedure we adopt to solve questions. Always remember that in order for an eye to see an image clearly, i) the rays from object to eye must not be obstructed, and ii) the point of incidence must be located on the actual mirror.
- For refraction: TIR occurs when i) light travels from optically denser to less dense medium, and ii) angle of incidence is bigger than critical angle. Always remember, in PMC, n2 is usually the optically denser medium.
Do remember to always bring your Secret Enclosed AND the revision books for all lessons.
What we received:
In this coming week (Aug 13, 15 and 16), we will continue our revision on Light II – Lens. Do remember to bring along your pencil and ruler for this lesson!!
Should you need assistance in your daily practices in Physics, do send your attempted workings and questions to 9100 1235. We will strive to clarify your doubts.
