🌈 How Light Travels and Reflects
This quiz explores how light travels in straight lines and reflects off mirrors. You'll learn to predict where reflected light goes using the angle of incidence, and discover real-world uses like periscopes and mirrors. Master the fundamentals of light behaviour! **What you'll learn:** - Light travels in straight lines - Reflection occurs when light bounces off surfaces - The law of reflection: angle of incidence equals angle of reflection - How flat mirrors and curved mirrors reflect light differently - Practical applications of reflection in periscopes and everyday mirrors

Answers hidden — play to find out.
- Question 1
What path does light take when it travels from a light bulb to your eyes?
- Question 2
When light hits a flat mirror, the angle at which it bounces off is always the same as the angle at which it hits the mirror.
- Question 3
If a light ray hits a flat mirror at a 30-degree angle from the normal line, at what angle will it reflect?
- Question 4
What happens when light reflects off a curved mirror that curves outward (like the back of a spoon)?
- Question 5
A periscope uses mirrors to allow someone to see over an obstacle by reflecting light multiple times.
- Question 6
In a periscope, if the first mirror reflects light upward at a 45-degree angle, what should the second mirror do?
- Question 7
Why do you see your reflection when you look into a flat mirror?
- Question 8
When light reflects off a curved mirror that curves inward (like the inside of a spoon), all the reflected rays meet at a single point.
- Question 9
If a light ray hits a mirror straight on (perpendicular to the surface), what will happen to the reflected ray?
- Question 10
What is the 'angle of incidence'?
- Question 11
A rough or bumpy surface will scatter light in many directions instead of creating a clear reflection like a smooth mirror does.
- Question 12
Which of the following best describes why we can see the Moon at night?
- Question 13
Why is a shiny, polished surface better for creating a clear mirror image than a dull, matte surface?
- Question 14
Light can bend and curve as it travels through air.
- Question 15
If you want to look around a corner without stepping out, which optical tool would be most helpful?
- Question 16
What do the angle of incidence and angle of reflection have in common?
- Question 17
Different colors of light reflect off mirrors in different ways.
