The document discusses how light interacts with different materials, categorizing them as transparent, translucent, or opaque. Transparent materials allow all light to pass through, like glass. Translucent materials allow some light to pass through in a blurred manner, like sunglasses lenses. Opaque materials do not allow any light to pass through, like a brick wall. The document provides examples of objects for each category and asks readers to identify materials as transparent, translucent, or opaque. It concludes with a homework assignment to bring in examples of each type of material.

1. HOW LIGHT INTERACTS WITH
OTHER OBJECTS!!
SOL 5.3C
Transparent, Translucent, and Opaque

2. IT ALL DEPENDS . . . . .
● As light travels, you know it hits many
objects.
● We have talked about how light reflects
(bounces) of some objects and is refracted
(bent) by other objects.
● Depending on what the object is made of,
light will interact in different ways.

3. TRANSPARENT MATERIALS
● Most people don’t want a
transparent shower
curtain or door!
● Why? You can see all the
way through it!!!
● Transparent materials let
ALL of the light that hits
them to pass through
them.
● Common transparent
materials are glass and
thin plastic.

4. TRANSLUCENT MATERIALS
● You can sort of see through
it, but not all the way.
● Translucent materials allow
SOME of the light that hits
them to pass through them.
● The images through
translucent materials
appear blurred or distorted.

5. OPAQUE MATERIALS
❖ You would probably
LOVE to have an
opaque curtain when
you are trying to sleep
in late!
❖ You cannot see
through opaque
materials.
❖ NONE of the light that
hits an opaque object
will pass through it!

6. YOU DECIDE . . . TRANSPARENT, TRANSLUCENT,
OPAQUE?
Sure, it’s opaque!!! No light goes through a
brick wall!

7. YOU DECIDE . . . TRANSPARENT, TRANSLUCENT,
OPAQUE?
● Sure, it’s transparent!
Virtually ALL the light
goes through a window!!
● It’s a good thing, because
we like to see through
them!!

8. YOU DECIDE . . . TRANSPARENT, TRANSLUCENT,
OPAQUE?
● Sure, it’s translucent!! Just some of the
light goes through the lenses!
● That’s why we wear sunglasses – to block
SOME of the light!!!

9. YOU DECIDE . . . TRANSPARENT, TRANSLUCENT,
OPAQUE?
❖ Sure, it’s
translucent! We
can some of the
woman behind the
glass, but she is kind
of fuzzy!
❖ Not really . . . SHE
isn’t
fuzzy, but her image
is!

10. YOU DECIDE . . . TRANSPARENT, TRANSLUCENT,
OPAQUE?
Sure, it’s opaque!!! Light can’t travel
through thick plywood!!!

11. YOU DECIDE . . . TRANSPARENT, TRANSLUCENT,
OPAQUE?
● Sure, it’s transparent!!! All of the light that
hits the lenses is passing through them!
● It’s a good thing, because glasses are
supposed to HELP us see.

12. YOUR HOMEWORK FOR TONIGHT!!!
❖ Very simple homework assignment for you
tonight.
❖ Tomorrow, please bring in the following:
➢ ONE opaque object.
➢ ONE translucent object.
➢ ONE transparent object.
➢ Be careful what you bring in! I don’t want
anything to break and hurt you!
