the distance between any two corresponding points on an adjacent wave.
What is Wavelength
Light that comes from the sun or a lightbulb
White light
This is a positively charged particle found at the center of an atom. Each element has the same number of these
What is a proton
A substance that is needed by all life on Earth
What is Liquid water
These are what go into a chemical reaction
What are Reactants
The smallest units of matter that retain the properties of an element, consisting of a nucleus surrounded by electrons.
What is an atom?
This is the color with the longest wavelength
What is Red
the production and discharge of something, especially gas or radiation.
What is emission
This is a threat for coastal areas due to climate change
What is flooding
These are what a chemical reaction makes
What is a Product
The process where a material takes in energy from waves and converts it into another form
What is absorption?
This is what a spectrometer does to light so that we can see individual wavelengths
What is splitting
A particle with no electric charge, located in the nucleus of an atom, playing a crucial role in the stability of the nucleus.
What is a neutron
41% of all amphibians are threatened with __________ due to climate change
What is extinction
Represented by the formula:
2 Hydrogen + Oxygen --> Water + Energy
What is Chemical Combustion
Bright lines on a black backdrop that show distinct wavelengths of visible light. We saw this when then the telescope was looking at the gas cloud but not at the light bulb
Emission Spectrum
We know what makes up the sun because the ___________ of the sun match the ___________ of certain elements
What is absorption spectra
This is the amount of time nuclear fusion can power the sun
A gas associated with rising global temperatures
What is Carbon Dioxide (CO2)
Represented by the chemical formula:
H + H --> He + neutron + energy
What is Nuclear Fusion
Dark lines against the continuous spectrum. We saw this when looking at the lightbulb through the gas cloud.
Absorption Spectrum
These are the two elements that make up our Sun
What is Hydrogen (H) and Helium (He)
This is the unit that we measure the energy output of the sun with
Mega Electron Volts (The sun releases 2.41 X 10^30 per second)
The amount of time that liquid water has existed on planet Earth
What is about 4 billion years
The creation of new nuclei (or elements)
What is nucleosynthesis
