Waves from the Sun
This type of energy transfer allows the Sun's energy to travel through empty space to Earth.
What is radiation?
These EM waves have the longest wavelengths and lowest frequencies.
What are radio waves?
This wave property tells how many waves pass a point each second.
What is frequency?
This type of wave is an example of a transverse wave.
What is a light wave?
When light bounces off a mirror, this occurs.
What is reflection?
The three main types of solar radiation that reach Earth are visible light, infrared, and ______ radiation.
What is ultraviolet (UV) radiation?
These EM waves have the shortest wavelengths and highest frequencies.
What are gamma rays?
As the frequency of an EM wave increases, its energy does this.
What is increases?
This type of wave is an example of a longitudinal wave.
What is a sound wave?
When light bends as it passes from air into water, this occurs
What is refraction?
Unlike sound waves, electromagnetic waves can travel through this.
What is a vacuum (empty space)?
Put these in order from lowest to highest frequency: Visible Light, Radio Waves, X-Rays.
What are Radio Waves → Visible Light → X-Rays?
As wavelength increases, frequency does this
What is decreases?
Sound waves need this in order to travel
What is a medium (matter)?
A black T-shirt gets warm in sunlight because it is doing this with light energy
What is absorbing the light?
The Sun emits many types of electromagnetic waves. The name for all these waves together is the electromagnetic ________.
What is the electromagnetic spectrum?
The only part of the electromagnetic spectrum that humans can naturally see.
What is visible light?
Which has more energy: an infrared wave or an ultraviolet wave?
What is ultraviolet light?
Why can astronauts communicate by radio but not by shouting in space?
What is radio waves travel through a vacuum but sound waves do not?
A prism separates white light into many colors because each color is refracted differently. This demonstrates that white light is made of many ________.
What are colors/wavelengths?
A student says sunlight is only visible light. Explain why this statement is incorrect.
What is "The Sun emits visible light, infrared radiation, ultraviolet radiation, and other electromagnetic waves"?
Name the seven regions of the electromagnetic spectrum from lowest frequency to highest frequency.
What are Radio, Microwaves, Infrared, Visible Light, Ultraviolet, X-Rays, Gamma Rays?
Two waves are compared:
Wave A: short wavelength
Wave B: long wavelength
Which wave carries more energy and why?
What is Wave A because shorter wavelengths have higher frequencies and greater energy?
Compare how light and sound travel.
What is light can travel through a vacuum and is a transverse wave, while sound requires matter and is a longitudinal wave?
A beam of light hits a window. Some passes through, some bends, and some bounces off. Name all three interactions occurring
What are transmission, refraction, and reflection?
