Science Flashcards
What do frequency energy have to do with each other?
The more energy there is, the higher the frequency is
What is the order of the electromagnetic spectrum?
Radiowaves Microwaves Infrared rays Visible light Ultraviolet rays X-rays Gamma rays
How do wavelength and energy relate to each other?
The less energy there is, the lower the wavelength
How do frequency and wavelength relate to each other?
If there is a high frequency the wavelength is low, if there is a low frequency the wavelength is high
