Seeing Stars
Many solar systems have two of these; many of them are larger than ours. Ours only looks large because of its closeness to us.
What is a star or the Sun?
Grass reflects this frequency of light and absorbs all others.
What is green?
When light is absorbed by any form of matter, it is transformed into this.
What is heat?
This is necessary for a sound to be made.
What is a vibration?
Solid carbon dioxide is also known as this.
What is dry ice?
This includes a star and everything caught in its gravitational field.
What is a solar system?
This is the saying that can help you remember the order of the visible spectrum?
ROYGBIV
EM radiation is the only form of energy that can travel through this.
What is the vacuum of space?
This is what we here when sound is reflected.
What is an echo?
A substance that is mixed with a solvent does this.
What is dissolve?
In scientific terms, the first one takes 365 days, and the second takes 24 hours.
What is the Earth's revolution and rotation?
A prism is an example of an object which causes light to do this.
What is refract?
This is the SI unit for frequency.
What is Hertz?
Sound travels fastest in this medium.
What is a solid?
In genetics, a term for something that influences, or prevails over other factors.
What is dominant?
This value depends upon a star's luminosity, its distance, and any dimming of light caused by interstellar dust along the line of sight of the observer.
What is apparent magnitude?
The first material lets light pass through, the second scatters light and the third blocks it?
What is transparent, translucent and opaque?
When the wavelength of EM radiation increases, the energy does this.
What is decreases?
Higher pitches have a higher one of these and lower pitches have a lower one.
What is frequency?
This occurs when an object is immersed in a fluid, pushing it out of the way and taking its place.
What is displacement?
Because of the Earth's rotation on its axis, we humans experience this.
What is day and night?
This is the result of our brain interpreting different visible wavelengths of light that are reflected back to our eyes.
What is color?
We can see objects because they do one of these two things with light.
What is emit or reflect?
When a sound doesn't create an echo, it's because the objects in a room are doing this.
What is absorbing sound?
A unit of measure of the loudness or volume of sound waves.
What is a decibel?
