What is the source of most light on Earth?

What is the largest island in the Hawaiian Island chain?
Hawai'i Island or Big Island
Waves passing through matter (is it transmission, absorption, or reflection)
Transmission
What happens when a material takes in light energy instead of allowing it to pass through?
Absorption occurs

The measurement on a wave from one point to the same point on the next wave is the _______________. (crest to crest, or trough to trough)
wavelength
What is the capital of Hawaii?

Reflection
Sound waves are caused by the ______________ of particles.
vibrations
The height of a wave from the rest line to the highest point on a wave is _______________.

Long Answer: Describe two types of electromagnetic waves.
Choose any two and describe: microwaves, radiowaves, infrared waves, ultraviolet waves, visible light waves, x-rays, gamma rays.
What travels faster light or sound?
Light
What happens to a sound when its amplitude increases?
Sound gets louder
Long Answer: You are slowly touching the surface of a pond with the tip of a stick. Waves spread out in concentric circles from the contact spot. Then you touch the water with the same force but more quickly. Identify the wave property you are changing most directly.
The number of waves produced per unit of time is increasing, so the wave frequency is the property most directly changed.
Which island is the most populated?
O'ahu
