Answer:
Waves carry energy from one place to another.
Because waves carry energy,some waves are used for communication,eg radio and television waves and mobile telephone signals.

Hi!
I think the oxidation state of all the atoms should change. :)
Hope this helps
Hey there!
Density = 2.70 g/cm³
Volume = 10.0 cm³
Therefore:
Mass = density * volume
Mass = 2.70 * 10.0
Mass = 27.0 g
Answer:
this is difficult but simple to answer
Explanation:
all atoms move in 1 direction no more than 2
Answer:
Here's what I get.
Explanation:
(b) Wavenumber and wavelength
The wavenumber is the distance over which a cycle repeats, that is, it is the number of waves in a unit distance.

Thus, if λ = 3 µm,

(a) Wavenumber and frequency
Since
λ = c/f and 1/λ = f/c
the relation between wavenumber and frequency is

Thus, if f = 90 THz

(c) Units
(i) Frequency
The units are s⁻¹ or Hz.
(ii) Wavelength
The SI base unit is metres, but infrared wavelengths are usually measured in micrometres (roughly 2.5 µm to 20 µm).
(iii) Wavenumber
The SI base unit is m⁻¹, but infrared wavenumbers are usually measured in cm⁻¹ (roughly 4000 cm⁻¹ to 500 cm⁻¹).
