Study Notes
How We See Objects
- We see objects because light waves bounce, or reflect, off them, a process called reflection.
- Light travels in a straight line from a source, hits an object, and then reflects off the object in a straight line to our eyes.
- The eye has special cells that can sense different colors of light, sending this information to the brain, allowing us to see.
How We See Objects in a Mirror
- In a mirror, light strikes the mirror at an angle and reflects off of it at the same angle.
- This is why what we see in a mirror depends on where we stand.
Light and Reflection
- Light travels in straight lines and cannot pass through walls.
- Light rays can be absorbed or reflected by objects.
- The direction of reflected light depends on the angle of incidence.
Mirrors and Perception
- A mirror reflects light, allowing us to see objects that are not directly in our line of sight.
- The position of the observer affects what we see in a mirror.
How We See Objects with Light Sources
- We can see objects when light rays from a source, such as the sun or a flashlight, reflect off the object and into our eyes.
- The presence or absence of light affects our ability to see objects.
- Low light conditions can affect our ability to see objects clearly.
How Do We See Objects?
- We see objects because light reflects from them and enters our eyes.
- Light travels in a straight line from a source, hits an object, and bounces back to our eyes.
- This process is called reflection.
Characteristics of Light
- Light is an electromagnetic wave.
- Humans can only see visible light, not other types of electromagnetic waves like radio waves or heat.
- Some animals can see other types of electromagnetic waves.
The Role of the Eye
- The eye has special cells that can sense different colors of light.
- The eye sends information to the brain, allowing us to see.
- Light cannot reach our eyes if they are closed or if something is blocking the light.
Mirrors and Reflection
- Light travels in straight lines, so when light strikes a mirror at an angle, it reflects off at the same angle.
- This is why what we see in a mirror depends on where we stand.
- Objects that reflect in a mirror appear to be in a different location than their actual position.
Seeing Objects in a Mirror
- When light rays reflect from an object and enter our eyes, we can see the object in a mirror.
Important Concepts
- Acute angles are less than 90 degrees, and obtuse angles are greater than 90 degrees.
- Folds along a line of symmetry can help determine the number of degrees in an angle.
