Explanation:

Given that,

The frequency of electromagnetic spectrum is 2.73\times 10^{16}\ Hz

(A) Let the wavelength of this radiation is \lambda. We know that,

c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{2.73\times 10^{16}}\\\\\lambda=1.09\times 10^{-8}\ m

So, the wavelength of this radiation is 1.09\times 10^{-8}\ m.

(B) Let E is the energy associated with this radiation. Energy of an electromagnetic radiation is given by :

E=hf

h is Planck's constant

E=6.63\times 10^{-34}\times 2.73\times 10^{16}\\\\E=1.8\times 10^{-17}\ J

1 kcal = 4184 J

It means,

1.8\times 10^{-17}\ J=\dfrac{1}{4184}\times 1.8\times 10^{-17}\\\\=4.3\times 10^{-21}\ \text{kcal}

Hence, this is the required solution.

How would you express the frequency of a wave in which five peaks passed a given point each second?
Pani-rosa [81]

n = number of peaks passed a particular point = 5

t = time taken by the peaks to pass a particular point = 1 sec

f = frequency of the wave

by definition , frequency is the repetition of an event in a given interval of time.

we know that frequency is given as

f = n/t

inserting the values

f = 5/1

f = 5 Hz

hence the frequency of the wave comes out to be 5 Hz
