Glowling — Light Sources & Seeing Palace Entry Court

Hi!

I'm Glowling.

Welcome to Palace Entry Court!

Will you help me investigate light sources & seeing?

The Grumblies have mixed up our clues.

Let's check the evidence!

A light source emits light.

Many objects are seen because light from a source reflects from them

and reaches our eyes.

Which is a light source in our model?

  • A. The lamp
  • B. The reflecting object
  • C. The object's name label

The answer is A: The lamp

A light source emits light.

Many objects are seen because light from a source reflects from them

and reaches our eyes.

That clue helps us make sense of this place.

A mirror or the Moon can reflect light without being

a source like a lamp or the Sun.

Seeing requires a light path, not eyes sending out viewing rays.

What path lets us see the object?

  • A. Eye to object with no incoming light
  • B. Object to lamp without reaching an eye
  • C. Lamp to object to eye

The answer is C: Lamp to object to eye

Our model traces lamp → object → eye.

The object becomes hard to see when that path is blocked.

Use the diagram;

never look at the Sun or a laser.

Hmm...

how does that connect to our first clue?

Our model traces lamp → object → eye.

The object becomes hard to see when that path is blocked.

Use the diagram;

never look at the Sun or a laser.

Does a reflector have to make its own light?

  • A. Only if shiny
  • B. No
  • C. Yes

The answer is B: No

A light source emits light.

Many objects are seen because light from a source reflects from them

and reaches our eyes.

Nice investigating!
