Microwave radiation has a wavelength on the order of 1.0 cm. Calculate the frequency and the energy of a single photon of this radiation. Calculate the energy of an Avogadro's number of photons (called as einstein) of this radiation.

Given that,

The wavelength of microwave radiation = 1 cm = 0.01 m

To find,

The frequency and the energy of a single photon of this radiation.

Solution,

Let f be the frequency of the wave. The relation between frequency and wavelength is given by :

Let E be the energy of the wave. The energy of the wave is given by :

We know that,

Energy :

Hence, this is the required solution.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
