Waves and Electromagnetism - Middle School Physical Science

The answer is mass. Waves are energy and do not have mass.

Energy takes two forms, particles and waves. Waves can be absorbed, reflected, refracted or even diffracted depending on the medium they interact with. It’s important to understand waves because we interact with them all the time. Think about microwaves, x-ray machines, eyeglasses, tsunamis in the ocean, radios and speakers. The properties of a simple wave are:

Wavelength: The distance between one point on a wave and the exact same place on the next wave
Wave frequency:the number of cycles an object or wave goes through in 1 second
Crest: the highest point on a wave Trough: the lowest point on a wave
Period:the amount of time for the harmonic motion to repeat itself, or for the object to go one full cycle
Amplitude: The distance from the equilibrium (or center) point of the wave to either its lowest or highest point
Speed: wavelength (in m) x frequency (in Hz). It varies in solids, liquids and gases.

Wavelength is the distance between one point on a wave and the exact same place on the next wave.

The answer is 1.75 Hz because the wave goes through 1.75 full cycles.

The answer is "the period" because wave speed is wavelength times frequency and you cannot calculate frequency without the period.

The answer is "when waves bend as they enter a new medium"

When waves approach objects they do not just stop or disappear. They can be reflected off the object, diffracted around the object, or transmitted through it (accompanied by refraction)! It all depends on the kind of wave, and the “medium” or type of object the wave is traveling through.

Reflection occurs when waves bounce back from a barrier they cannot pass through. An echo is an example of wave reflection. Reflection can happen with any type of waves, not just sound waves.

Refraction occurs when waves bend as they enter a new medium at an angle. For example, light bends when it passes from air to water.

Diffraction occurs when waves spread out, move around, or pass through an opening in an obstacle. All waves may be diffracted, but it is more pronounced in some types of waves than others. For example, sound waves bend around corners much more than light does. That’s why you can hear but not see around corners.

The answer is diffraction.

The answer is "the pencil appears to be broken because the light waves are being refracted as they enter the water."

The answer is "less light is refracted and reflected off the air around the fire." This would cause less image distortion.
