refraction Flashcards
1
Q
what is refraction
A
WHEN WAVES ENTER A NEW MEDIUM (MATERIAL), THEIR SPEED CHANGES. AS DOES THEIR ANGLE.
2
Q
what happens to the wavelength and frequency if the speed decreases
A
wavelength decreases and frequency stays consistent
3
Q
what happens if the wave slows down
A
If the wave slows down, it bends TOWARDS the NORMAL (e.g. when going from air into any material).
