What does water and prisms effect light compared to mirrors

• Water, prisms, and mirrors all reflect and refract light

• Water and prisms reflect and refract light, mirrors only reflect.

• Mirrors and prisms only reflect light and water refract.

• Water, prisms, and mirrors only refract light.

We see visible light as different colors of the rainbow. Each color has the same wavelength of light. Which statement correctly explains the relationship between wavelength and color of light?

• A we move from violet to red, the wavelength lengthens and less energy

• As we move from violet to red, the wavelength shortens and less energy

• As we move from violet to red, the wavelength lengthens and no change

• As we move from violet to red, the wavelength shortens and more energy

What makes an object appear green?

• the object absorbs green wavelengths and reflects all the other colors.

• the object absorbs green wavelengths and absorbs all the other colors

• the object reflects green wavelengths and reflects all the other colors

• the object reflects green wavelengths and absorbs all the other colors

What can reflect and refract light?

• water

• opaque

• translucent

• transparent

What is the difference between the different types of electromagnetic radiation in the visible spectrum?

• The ability to transmit and therefore the wavelengths of the types of electromagnetic radiation are different.

• The amount of energy and therefore the wavelengths of the types of electromagnetic radiation are different.

• The amount of refraction and therefore the wavelengths of the types of electromagnetic radiation are different.

• The ability to reflect and therefore the wavelengths of the types of electromagnetic radiation are different.

A prism effects white light. How does a prism effect white light and why does this occur?

• White light enters the prism. As the light exits, the prism transmits the light and separates it into a display of colors.

• White light enters the prism. As the light exits, the prism reflects the light and separates it into a display of colors.

• White light enters the prism. As the light exits, the prism absorbs the light and separates it into a display of colors.

• White light enters the prism. As the light exits, the prism refracts the light and separates it into a display of colors.

Light passes through some objects partially. These objects are classified as _________ objects.

• translucent

• absorbed

• transparent

• opaque
