Optical Illusions
How do we see objects?
How are shadows created?
Reflection. of light
Light sensors/ models
100

This type of illusion makes still images appear to move because of the arrangement of colors and shapes.

what is motion illusions 

100

This part of the eye focuses light onto the retina.

What is the lens

100

A shadow is formed when this object blocks light.

what is an opaque object?

100

This law states that the angle of incidence equals the angle of reflection.

what is the law of reflection 

100

This type of light sensor is used in streetlights to detect when it gets dark.

what is a light sensor

200

This famous optical illusion features two colors that some people see differently, like blue and gold.

what is color perception 

200

This layer of the eye contains photoreceptor cells responsible for detecting light.

What is the retina

200

This effect explains why objects appear to cast longer shadows during this time of day.

what is the angle of the sun 

200

This type of mirror curves inward and can produce magnified images.

what is a concave mirror

200

This sensor detects colors and is often used in printers to read color.

what is a color sensor

300

When colors seem different because of the colors around them, this is called this phenomenon.

what is color constancy

300

These cells in the retina help us see in low light and detect movement.

what are rod cells 

300

The sharpness of a shadow depends on this aspect of the light source.

what is the size of a light source

300

A flat surface reflects light at the same angle, while this curved surface can focus light to a point.

what is a concave surface

300

This type of model can show how light reflects off surfaces and helps explain angles of incidence and reflection.

what is a physical model

400

Random.

What class is this? 

(free point) 

400

These cells in the retina allow us to see colors and details.

what are cone cells

400

When the sun is low in the sky, shadows appear this direction.

what is the opposite direction of the light source

400

When the sun is high in the sky, shadows will appear this direction.

what is directly below the object

400

Models of the eye illustrate how light travels through these parts, helping us understand how we see.

what is the lens and renita 

500

This illusion involves a pattern where lines appear warped or curved, despite being straight.

what is the café wall illusion

500

This part of the eye sends signals to the brain so we can understand what we see.

what is the optic nerve

500

These visual aids can demonstrate how shadows are formed when an object blocks light

what is a shadow model

500

This term describes how different materials affect how light passes through them, such as transparent or translucent.

what is transmission

500

These visual aids can demonstrate how shadows are formed when an object blocks light
