Light Waves test Prep

How can we keep track of movement of energy?

• We can observe if the object changes color.

• We can observe if the material changes.

• We can measure the color of the light wave.

• We can ask Mr. Porter for the correct answer.

How can light cause materials to change?

• Objects can take in energy, which can cause a change.

• Light can go through objects which can cause a change.

• Objects can reflect light, which can change them.

• Objects can transmit light and energy, which can cause a change.

When light travels towards an object and hits it, why will the material sometimes change?

• The material will change when the energy is transmitted.

• The material can only change if energy is absorbed.

• If the energy is reflected the material will change.

All light carries energy as it travels, select the following option that best describes how materials can change when they absorb energy.

• Different lights carry the same energy which causes materials to all change the same.

• All materials are changed by energy in the same way.

• Different lights carry the same type of energy which can cause the same changes.

• Different lights carry different energy which can cause different changes.

The sun is an example of a light source, which of the options below correctly describes the sun.

• The sun emits both visible and invisible light.

• The sun emits yellow light only.

• The sun only emits visible light.

Which variable correctly describes how one light wave can become a different light wave. For example, how would a scientist working with a laser change the light from blue light to ultraviolet.

• Changing the Amplitude of the wave

• Changing the frequency of the wave

• Changing the wavelength of the wave.

• Changing the distance between the two peaks of the wave.

A student is experimenting with a light bulb that emits sunlight and a plant. Which of following correctly describes how the emitted light and plant interact together?

• The plant absorbs all energy from the sun.

• The energy from the sun is ONLY absorbed or transmitted through the plant.

• The plant reflects energy from green light.

• The plant only absorbs energy from green light.

A student is experimenting with a red laser in class using a spray bottle and different objects. They want to know if it’s possible to create a curved beam of red light. Select the procedure that will create a curved beam of light.

• The student should point the laser into their friend's eyes.

• The students should point the laser at a mirror.

• The students should point the laser through a plastic cube that will transmit light.

• It will not be possible to create a bent light.

Mr Collins ran an experiment with a light bulb that only produced visible light and clear pieces of glass from the window. All light that emitted from the bulb was transmitted through the material. During the experiment will it be safe for Mr. Collins to pick up the piece of glass?

• No he should not pick up the glass because the glass may burn his hands due to the temperature of the glass increasing.

• Yes he should but there is a potential for the glass to break because is may have been damaged by the light.

• Yes it will be safe to pick up the glass.
