Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, that is, in the range 10 nm to <span>400 nm</span>
Frequency of a wave =
(speed of the wave) divided by (wavelength)
or
(1) divided by (period of the wave) .
Period of the wave =
(wavelength) divided by (speed of the wave)
or
(1) divided by (frequency of the wave) .
The molecules spread apart, so they take up more space. Because of this, they are less dense.
This means the density decreases as temperature increases.
Answer:
Explanation:
25 cycles/s (5 s) = 125 dots
Tape does Repetitious motion.
It might possibly be harmonic motion, but we do not have enough information to say for certain.
