Radiation Flashcards
Which color of visible light has the highest frequency? Red or Blue?
Blue
When increasing the frequency of light, what will happen to :
Wavelength:
Speed:
Wavelength: It will decrease
Speed: Stays same
where on the electromagnetic is
Gamma rays
Infrared rays
Radio waves
Gamma rays: highest energy on the left
Infrared: Right of visible light
Radio waves: lowest energy Right
What color has the shortest wavelength
Blue
What type of waves has the least energy
Radio waves
Why does an object that is in water or other liquids appears to be “broken”
Refraction occurs due to the speed of the light wave going through the water.
When increasing the frequency of light, what will happen to,
Wavelength
speed
Wavelength: it will decrease
Speed: Stay the same
Which color of visible light has the highest frequency? Red or Blue?
Blue
Which color has the shortest wavelength
Blue
What waves have the least amount of energy
Radio waves
Why does an object in water look “Broken”
Refraction occurs when the speed of the light wave goes through the water
Explain how the photoelectric effect changes when the color of light changes
The higher frequency of the light the more electrons fly off making a better photoelectric effect
does ultraviolet do damage?
UV rays can damage living cells because it strips electrons
What happens when the left side of the spectrum hits you (Xrays) does it damage cells through ionization?
Yes xrays damage cells through ionization
Why is some radiation dangerous?
Some radiation is dangerous because it can strip electrons from atoms and can cause cancer
