SPM Physics: AHA! Refraction Needs an Angle

 

Same glass, different result! Why?

• When the angle of incidence i=0∘, the ray passes straight through — no refraction.

• When i>0∘, the ray bends towards the normal — refraction occurs.

Exam tip: Refraction only happens when light enters another medium at an angle to the normal. Don’t just memorize “light bends.” Write the scoring clue: i > 0° → refraction visible.

This comic shows students that physics is about conditions. Same material, same setup, but different angle gives different outcome.

AHA! No angle, no bend. Not by sight, but by INSIGHT!

SPM Physics: AHA! Scarecrow Shows Invisible Air

 

Growing up in KL city, I never saw a scarecrow. Only after graduating and being posted to Sarawak did I witness them in real life. Here, scarecrows are closely tied to the indigenous community — a must for farming.

At a cultural exhibition, I saw scarecrows on display and was inspired to create this comic. Physics explains:

• Air is invisible, but wind makes its effect visible.

• Moving air exerts a force on straw fibres and grass.

• The bending and dancing of straw show that a force is acting.

Exam tip: don’t write “the straw moves by itself.” The scoring clue is moving air exerts a force.

AHA! Wind unseen, force revealed. Not by sight, but by INSIGHT!

SPM Physics: AHA! Lun Bawang Bamboo Music = Physics Notes

 

Readers, have you heard of the Lun Bawang people? In their language, “Anum Bala” means “How are you?” I once attended their traditional cultural night and was fascinated by their signature bamboo music instrument.

Physics explains the beauty:

• Longer bamboo tube → Lower pitch (lower frequency).

• Shorter bamboo tube → Higher pitch (higher frequency).

• The frequency depends on the length of the vibrating air column.

Exam tip: don’t confuse pitch with loudness. The scoring clue is longer tube = lower pitch, shorter tube = higher pitch.

This comic connects culture with science: same material, different length, different note. Physics is everywhere — even in Sarawak’s Lun Bawang heritage.

AHA! Bamboo length shapes sound. Not by sight, but by INSIGHT!

SPM Physics 2026: AHA! Time to Take Off!

 

From LEGO jets to real exam jets — the message is clear: SPM is near, it’s time to take off.

• Fighter jets rely on streamlined design to overcome drag.

• Students rely on past year practice to overcome exam stress.

• Both need preparation, focus, and insight to soar.

So, don’t wait. Plan your revision, practise output learning, and trust your preparation.

AHA! Exam season is take‑off (起飞）season. Not by sight, but by INSIGHT!

SPM Physics: AHA! Fruit Basket Challenge

 

Walking past the fruit wholesale shop, I was drawn not only by the colorful baskets but also by the mysterious words carved on them. I realized fruit baskets are more than just containers — they’re versatile tools. I use them for books, for storage, for daily life.

This inspired the latest AHA! comic: The Fruit Basket Challenge. It’s not about the brightest color or the heaviest basket. Engineers look for low mass and high strength — materials that are lightweight, durable, and resilient enough to survive the sea journey to Miri.

Exam tip: don’t fall into the trap of thinking “heavier = stronger.” The scoring clue is strong, durable, and lightweight.

AHA! Low mass, high strength. Not by sight, but by INSIGHT!
