Tabitha wants to study how light moves. She aims a beam of white light at a prism. Which picture most likely shows how the light will act ones it reaches the prism?
When light enters a prism, it
increases in speed
refracts and bends
reflects off the surface
continues in a straight line
To learn more about light, Joey shines a light through a prism. What does he notice happens to the light when it enters the prism?
The ray of light straightens as it strikes the glass.
The ray of light transforms to heat when it strikes the glass.
The ray of light bends as it strikes the glass.
The ray of light becomes shorter when it strikes the glass.
Hayden was conducting an investigation to see how light interacts with various objects. He recorded his results in one of the tables below. Which table shows what he most likely found in his investigation?
Mary is carrying out an investigation to determine the best material to use for shadow puppet in order to create the best shadow. A shadow puppet works by shining a light on the puppet and casting a shadow. Which conclusion did Mary most likely make from her investigation?
tissue paper because it is transparent
wax paper because it is translucent
clear plastic because it is opaque
cardboard because it is opaque
Ali wants to investigate what happens when a ray of light travels through the lens of a pair of glasses that someone is wearing. Based on her investigation, what could she conclude happens to the light ray when it travels through the lens?
It causes light to move only away from a person's eye, making it easier for them to see an object.
It absorbs light and stops damaging light rays from getting through to a person's eye.
It makes light travel in a straight path through the lens making it brighter.
It causes light to change direction toward the location needed for a person to see.
Erika is investigating the path light will travel when a light source is shined on a mirror. Which diagram shows the results of her investigation?
Willow is performing an investigation using a flashlight on a transparent object. Which picture most likely shows the results of her investigation?
A student has two objects (object W and object X) that she wants to identify as translucent, transparent, or opaque. She deiced to conduct an investigation by shining a flashlight through each object and observing the results. The picture show the two objects with light shining through them. Which sentence correctly identifies the objects?
Object W is opaque and object X is translucent.
Object W is transparent and object X is opaque.
Object W is translucent and object X is transparent.
Object W is transparent and object X is translucent.
Maya builds a device that uses a flashlight and a reflective surface to point the beam of light in different directions. The picture shows her device. Which of the materials below should Maya use as a reflective surface to BEST reflect the flashlight's beam?
mirror
cardboard
plastic wrap
tissue paper
A beam of light was shone on six different materials. The percentage of the light that went through each material is listed in the table. Which of the following tables correctly classifies the materials?
Glass is made from sand, which is itself made up of tiny rocks and minerals. While it has many uses, glass is often used for windows. Which of the following best explains why windows are made of glass rather than a natural resource, such as wood?
Glass is hard and strong, while wood is not.
Glass is transparent, while wood is not.
Glass can be bent, while wood cannot.
Glass absorbs water, while wood cannot.
Light travels in waves. Which of the following statements about light waves is NOT true?
They can come from sources across space.
They can travel through any type of material.
They travel in straight lines from their sources.
They can be reflected by some types of materials.
To better understand how light travels, Javon is studying his reflection in the mirror as shown in the picture. Which statement describes why Javon can see himself in the mirror?
Light bends straight up along the mirror and goes away from Javon.
Light is being absorbed by the mirror that then makes a picture of Javon.
Light travels through the other side of the mirror to make a picture of Javon.
Light that is traveling in a straight line hits the mirror and goes back toward Javon.
Which of the following is true about the direction light travels after hitting a mirror?
It travels straight north after hitting the mirror.
It travels straight through the mirror to the other side.
It reflects out at random angles that cannot be predicted.
It reflects out at the opposite angle from which it hit the mirror.
Daniel shines a light on a mirror at an angle, as shown in the picture. The arrow shows the path of the light as it is reflected by the mirror. What is the measurement of the angle that completes this model?
10°
20°
40°
80°
A student is investigating how sunlight interacts with two different materials, plastic wrap and wax paper. The picture shows the materials taped to the window on a sunny day. Which sentence correctly classifies the two materials based on how much sunlight passes through them?
The plastic wrap is transparent, and the wax paper is opaque.
The plastic wrap is translucent, and the wax paper is transparent.
The plastic wrap is opaque, and the wax paper is translucent.
