🪞 Reflection and Mirrors
Explore how light reflects off different surfaces and how mirrors create images. This quiz covers the science of specular and diffuse reflection, the behavior of light rays bouncing off smooth and rough surfaces, and how different types of mirrors—plane, concave, and convex—are used in everyday life. Perfect for Grade 4 learners developing their understanding of light and optics. **What you'll learn:** - The difference between specular reflection (smooth surfaces) and diffuse reflection (rough surfaces) - How light reflects at equal angles using the law of reflection - How plane mirrors create images and why - The unique properties and real-world applications of concave and convex mirrors
Questions in this quiz
Answers hidden — play to find out.
- Question 1
When light hits a smooth, shiny surface like a mirror, what happens to the light rays?
- Question 2
What is the main difference between specular reflection and diffuse reflection?
- Question 3
A rough surface like sandpaper will produce diffuse reflection, scattering light in many directions rather than creating a clear image.
- Question 4
If a light ray hits a mirror at a 30° angle from the surface, at what angle will it reflect?
- Question 5
What type of mirror do you use to see your reflection in a bathroom?
- Question 6
A plane mirror always creates a real image that you can project onto a screen.
- Question 7
A concave mirror curves inward like a bowl. What is one real-world use of a concave mirror?
- Question 8
A convex mirror curves outward like the back of a spoon. What is a real-world use of a convex mirror?
- Question 9
A concave mirror can create a magnified image of an object placed close to it.
- Question 10
Why does a mirror image appear to be the same distance behind a plane mirror as you are in front of it?
- Question 11
Which of the following surfaces would create the most diffuse reflection?
- Question 12
The law of reflection applies to all types of mirrors: plane, concave, and convex.
- Question 13
What makes a mirror different from a window in terms of light reflection?
- Question 14
If you place a candle in front of a concave mirror, where would the real image form?
- Question 15
A convex mirror always creates a smaller, virtual image of the object.
- Question 16
Why is a smooth, polished surface better for creating a clear reflection than a rough, scratched surface?
- Question 17
In which situation would you want to use a concave mirror instead of a plane mirror?
