Answer:
shorter wavelength = alpha wave
Explanation:
Given that,
The alpha wave has a frequency of 5 Hz and the beta wave has a frequency of 2 Hz.
We need to compare the wavelengths of these two waves.
For alpha wave,

For beta wave,

From the above calculations, we find that the wavelength of the alpha wave is shorter than the wavelength of the beta wave.
Answer:
Ethane would have a higher boiling point.
Explanation:
In this case, for the lewis structures, we have to keep in mind that all atoms must have <u>8 electrons</u> (except hydrogen). Additionally, each carbon would have <u>4 valence electrons</u>, with this in mind, for methane we have to put the hydrogens around the carbon, and with this structure, we will have 8 electrons for the carbon. In ethane, we will have a bond between the carbons, therefore we have to put three hydrogens around each carbon to obtain 8 electrons for each carbon.
Now, the main difference between methane and ethane is an <u>additional carbon</u>. In ethane, we have an additional carbon, therefore due to this additional carbon, we will have <u>more area of interaction</u> for ethane. If we have more area of interaction we have to give <u>more energy</u> to the molecule to convert from liquid to gas, so, the ethane will have a higher boiling point.
I hope it helps!

Answer:
The maximum wavelength of light for which a carbon-hydrogen single bond could be broken by absorbing a single photon = 290 nm
Explanation:
So to break a single C - H bond require = 
= 6.84 x 10⁻¹⁹ joule
Find the wavelength of a photon we use E = hν
⇒ E = 
Where h = Planck's constant = 6.626 x 10⁻³⁴ J.K⁻¹.Mole⁻¹
c = speed of light = 3 x 10⁸ m/sec
Wavelength = 
= 2.9 x 10⁻⁷ m
= 290 nm
∵ 1 nm = 10⁻⁹ m
