How do light waves behave when they strike an object? Visible light waves How do light waves behave when they strike an object?

Light waves vocabulary Absorbed:

Light waves vocabulary Absorbed: Light is taken in and goes nowhere.

Light waves vocabulary Absorbed: Light is taken in and goes nowhere. Reflected:

Light waves vocabulary Absorbed: Light is taken in and goes nowhere. Reflected: Light is taken in and bounces off.

Light waves vocabulary Absorbed: Light is taken in and goes nowhere. Reflected: Light is taken in and bounces off. Transmitted:

Light waves vocabulary Absorbed: Light is taken in and goes nowhere. Reflected: Light is taken in and bounces off. Transmitted: Light is taken in and passes through.

Light waves vocabulary Opaque:

Light waves vocabulary Opaque: Light does not pass through. Light is either absorbed or reflected.

Light waves vocabulary Opaque: Light does not pass through. Light is either absorbed or reflected. Transparent:

Light waves vocabulary Opaque: Light does not pass through. Light is either absorbed or reflected. Transparent: Light passes straight through an object.

Light waves vocabulary Opaque: Light does not pass through. Light is either absorbed or reflected. Transparent: Light passes straight through an object. Translucent:

Light waves vocabulary Opaque: Light does not pass through. Light is either absorbed or reflected. Transparent: Light passes straight through an object. Translucent: Light passes through an object but objects on other side are blurred / jumbled.

Black Paper                                           

Black Paper The paper is considered opaque.                                            Light was absorbed.

Mirror                                                                      

The mirror is opaque. The light is reflected. Mirror                                                                      

Window                                                                                                

The window is transparent. The light is transmitted. Window                                                                                                                           

Wax-paper                                                                                                

Wax-paper The wax-paper is translucent. The light is transmitted but “jumbled”.                                                                                                                                                              

Reflection vs. Refraction

Reflection vs. Refraction Light bouncing off of a surface.

Reflection vs. Refraction Light bouncing off of a surface. Light bends because it changes speeds as it changes mediums.

Reflection vs. Refraction Light bouncing off of a surface. Light bends because it changes speeds as it changes mediums.

Reflection vs. Refraction Light bouncing off of a surface. Angle of incidence = Angle of reflection Light bends because it changes speeds as it changes mediums.
