FORMS OF ENERGY
This is defined as the ability to do work.
What is energy?
Waves transfer this from one place to another.
What is energy?
ound is energy caused by these.
What are vibrations?
The only form of solar energy directly received from the Sun by Earth is this.
What is light energy (radiation)?
Light bouncing off a surface is called this
What is reflection?
his type of energy is stored energy
What is potential energy?
The substance through which a wave travels is called a ______.
What is a medium?
Sound must travel through this.
What is a medium?
his part of the electromagnetic spectrum can be seen by human eyes
What is visible light?
The bending of light as it moves into a different medium is called this
What is refraction?
Energy of motion is called this.
What is kinetic energy?
The number of waves that pass a point per second is called this
What is frequency?
Light waves travel as this type of wave
What is a transverse wave?
Which electromagnetic wave has the longest wavelength and lowest frequency?
What are radio waves?
When white light passes through a prism, what causes the colors to separate?
What is refraction?
Energy stored in the bonds between atoms and molecules is called this form of energy.
What is chemical potential energy?
Unlike light waves, sound waves are classified as this type of wave.
What is a compressional (longitudinal) wave?
Sound travels fastest through which state of matter?
What is a solid?
his type of electromagnetic radiation is associated with heat or thermal energy.
What is infrared radiation?
Why does a black shirt become hotter in sunlight than a white shirt?
What is the black shirt absorbs more light while the white shirt reflects more light?
A battery powers a flashlight that produces light and heat. Identify the energy transformations that occur (MUST NAME 4)
What is chemical energy → electrical energy → light energy → thermal energy?
A wave has a frequency of 50 Hz and a wavelength of 4 m. Using the formula in the notes, what is the wave speed?
What is 200 m/s? (Wave Speed = Frequency × Wavelength)
An astronaut outside a spacecraft sees an explosion but hears nothing. Explain why.
What is sound cannot travel through the vacuum of space because there is no medium for the vibrations to move through?
Rank these from lowest frequency to highest frequency: X-rays, Microwaves, Radio Waves, Gamma Rays
What are Radio Waves → Microwaves → X-rays → Gamma Rays?
