Question 1

Schrödinger’s Cat

A thought experiment illustrating the concept of quantum superposition, where the cat is simultaneously both alive and dead until observed.

Question 2

Sound in Space

Sound cannot travel through space because space is a vacuum and lacks the matter (like air) for sound waves to propagate through.

Question 3

Rainbow Formation

Answer 3

It is an optical phenomenon caused by the refraction and reflection of sunlight within water droplets in the Earth’s atmosphere.

Question 4

The Doppler Effect

Answer 4

The change in frequency of a wave (like sound) in relation to an observer who is moving relative to the wave source (e.g., a siren getting higher-pitched as it approaches).

Question 5

Answer 5

A region of spacetime where gravity is so strong that nothing, including light, can escape from it.
