Which of the following has the shortest wavelength?
Gamma rays
The color blue
AM radio
Infrared
Which of the following has the highest frequency?
TV
microwaves
the color indigo
ultraviolet rays
A ___ is used in astronomy to break down light like a prism.
telescope
spectroscope
stethoscope
microscope
Each element on the periodic table can be identified by its
classification as a solid, liquid or gas.
location on the table.
ability to react to form compounds.
unique spectral "fingerprint."
What can you use to see all the different colors in white light?
A flashlight
A shadow
A camera
A prism
What do all forms of electromagnetic radiation have in common?
Their strength
Their speed
Their wavelength
Their frequency
What is the electromagnetic spectrum?
consists of all the different wavelengths of electromagnetic energy, including radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays, and gamma rays.
Spectrum produced by the emitted radiation
When sunlight is passed through a prism, it gets dispersed into continuous bands of different colors
all of this is part of the EM spectrum
Why do all types of electromagnetic energy not reach the Earth’s surface?
All types of EM energy do reach Earth's surface.
Our atmosphere blocks out harmful energy like X-rays, gamma rays and most ultraviolet rays, infrared, and low energy radio waves
No EM energy can penetrate through Earth's surface.
Gamma rays are the only energy that can't reach the surface.
In which list are forms of electromagnetic energy arranged in order from longest to shortest wavelength?
Microwave -> Radio wave -> Infrared rays
Visible light -> x-ray -> radio wave
Microwave -> infrared -> visibile light
Infrared -> radio wave -> ultraviolet

What happens when you shine a light through a prism?
The prism absorbs the light
The amount of light is low density
There is a continuous spectra of light
