How are wavelength and frequency related?

A low frequency wave has a long wavelength.

A low frequency wave has a short wavelength.

A high frequency wave and a low frequency wave have the same wavelengths.

Which is NOT true about light?

When white light is separated by a prism, the colors appear in a random order.

Light travels in a straight line until it strikes an object.

The way light reacts when it strikes an object depends on the properties of that object.

As white light passes through a prism , it bends and separates into different colors

Ultraviolet light is often used to sterilize water in a water treatment facility. Which is NOT a reason why?

Its energy level is high enough to cause damage to DNA and molecules.

It has wavelengths too large to cause molecular changes to the molecules of water.

Its wavelengths are small enough to affect bacteria and viruses.

If you put a pencil in a cup of water, it looks as if it is bent and larger in the water. This is because waves

change direction when they change mediums.

are absorbed instead of reflected.

bend around a barrier, like light does.

The golden arches of a McDonald's sign appear yellow because

The arches reflect yellow light more than any other color.

The arches absorb only yellow light from the sun.

Yellow objects reflect all colors except yellow.

Why is it difficult to see outside at night?

Without a light source, objects cannot reflect light to the eyes to be seen.

Objects become their own light sources in the presence of the Sun.

Human eyes are only able to see objects when sunlight creates shadows.

At night, objects absorb light instead of reflect it, so the eyes are unable to see.

Three cards with holes are arranged in a straight line. A light is shined through the first card’s hole and travels through all three cards. What does this demonstration tell you about light rays?

Light travels in a straight line

Light does NOT travel in a straight line

If you replace your house's tile floor with carpet, it will be

quieter, because soft surfaces absorb sound waves

louder, because sound waves bounce around more with carpet

louder, because soft surfaces amplify noises

quieter, because your tile was ugly

You look at a piece of red paper under two different lights - red light and white light. What do you see?

Red paper will appear red under both red and white light.

Red paper will appear red under red light and white under white light.

Red paper will appear black under red light and red under white light.

Red paper will appear red under red light and black under white light.

Rusty, the fastest cat in the universe, runs by faster than the speed of sound. You see her before you hear the sonic boom. Why?

Light travels faster than sound.

Your eyesight is better than your hearing.

Sound travels faster than light.

A large dog makes a low pitched sound and a tiny dog makes a high pitched sound. Which statement accurately describes the wavelengths of the two sounds?

The wavelength of the low pitched sound is longer than the wavelength of the high pitched sound.

The wavelengths of the two sounds are the same.

The wavelength of the high pitched sound is not measureable.

The wavelength of the low pitched sound is shorter than the wavelength of the high pitched sound.

Ronald played two sounds on his flute. For the first sound, he used only a little force. For the second sound, he used a lot of force. Based on the evidence provided, explain what you hear.

The second flute sound is louder than the first.

The first flute sound has a higher pitch than the second.

The two flute sounds are the same because they are the same note.

The second flute sound has a lower pitch and is louder than the first sound.

Which correctly describes the waves?

Wave B has twice the energy because it has an amplitude twice as large.

Wave A has twice the energy because it has a frequency twice as large.

Wave A has twice the energy because it has an amplitude twice as large.

Waves A and B gave the same energy because they have the same amplitude.

A simple model for how a door peephole works is shown here. How should letters A and B be labeled?

A is a convex lens and B is a concave lens.

Both A and B are convex lenses.

Both A and B are concave lenses.

A is a concave lens and B is a convex lens.

A concave lens is shown here. According to the model, a lens disperses (spreads) rays after they pass through it. Which item most likely uses a concave lens to perform its typical function?

a flashlight that emits light over a large surface

a microscope that focuses an image for easy viewing by the observer

a camera lens that focuses the light onto a magnetic or digital plate

a laser pointer that allows a single point of light to light up a surface
