Answer: Option (B) is the correct answer.

Explanation:

The given compound is K_{2}SO_{4}, that is, it contains potassium (K^{+}) and sulphate (SO^{2-}_{4}) ions.

Charge on a sulphate ion is -2 and charge on two potassium ions is +2. Therefore, according to cross multiplication method it results in the formation of K_{2}SO_{4}.

Thus, we can conclude that chemical name of the compound is potassium sulfate.

ch4aika [34]
A wave with low energy will also have long wavelengths and low frequencies.

The given in a single photon of a wave is given by Planck's equation:
E = hc/λ
and
E = hf

Where λ is the wavelength and f is the frequency of the photon. This means that energy is directly proportional to the frequency and inversely proportional to the wavelength. Thus, it is visible that photons with a lower frequency and a longer wavelength will have a lower energy.
