Physics 6.3.4 Flashcards
Each Colour within the Visible Light Spectrum Corresponds to a narrow band of ___ & ___.
Wavelength, Frequency.
Which Colour has the Longest Wavelength?
Red.
Which Colour has the Shortest Wavelength?
Violet.
The Wavelength and the Frequency/Energy of any Wave are ___ Proportional.
Inversely. Long Wavelength = Low Frequency / Energy.
Waves with Shorter Wavelengths have Higher ___, More ___, and Higher ___ Power.
Frequency, Energy, Ionising.
The Higher the Frequency of a Wave, the Higher the ___ of the Wave.
Energy.
The Frequency of a Wave is ___ Proportional to the Energy of the Wave.
Directly.
The Most Harmful Waves are the ones with the…
Highest Ionising Power.
Waves with High Energy May not Always be the Most Harmful Waves. Why?
Because they Do Not Have the Highest Ionising Power.
Why do Pregnant Women get Ultrasounds Done Instead of X-Rays? (3)
-X-Rays Have Shorter Wavelengths than Ultrasound,
-So Have Higher Ionising Power than them.
-So they are More Harmful to the Mother & the Baby.
Wavelength and Ionising Power are…
Inversely Proportional.
The Shorter the Wavelength, the ___ the Ionising Power.
Higher.
The Higher the Wavelength, the ___ the Ionising Power.
Shorter.
All Gamma Rays Will Have ___ Wavelengths than all Radio Waves, ___ Ionising Power than all Radio Waves, & ___ Energy than all Radio Waves.
Shorter, Higher, Higher.
An Increase in ___ is a Decrease in Frequency (Towards the ___ End of the Spectrum).
Wavelength. Red.
