Smart Glass Flashcard

Front

How is smart glass designed to interact with light when turned "On?"

Back

The material in the glass allows light to be transmitted so the glass looks transparent/clear.

Front

A student predicts that the smart glass might change the brightness of light when it passes through the medium. Which of the images shown above correctly models this change in light?

Back

Show the light as a wave and have the wave's amplitude decrease as it passes through the medium.

Front

Which of the student models of a smart window shows the "off" window interacting with light in a way that would prevent objects on the other side from being visible?

Back

Nora and Monique's models, because the models show the light hitting the glass and not passing through the material.

Front

A student is having a difficult time thinking of X-rays and infrared as abstract concepts. How can we think of X-rays and infrared?

Back

In a way, we can think of X-rays and infrared as light waves we cannot see.

Front

Which type of image will a flat mirror produce?

Back

same size and right side up

Front

Passenger-side mirrors on cars state "objects in mirror are closer than they appear." What causes this effect?

Back

The mirrors are convex.

Front

How does the shape of a spoon cause an image to differ between the inside and the outside?

Back

Light is reflected at different angles on each side of the spoon.

Front

What happens to an image in a concave mirror when the image goes beyond the mirror's focal length?

Back

The image flips upside-down.

Front

Rough surfaces do not make good mirrors because

Back

rough surfaces scatter light rays in different directions

Front

Which characteristic of a mirror makes it possible to predict information about the images it produces?

Back

its shape
