Question

The frequency of light for 1.0 A° wavelength is :- a. 3×10^18Hz b.3×10^18 / sec c.3×10^18 cycles per second d. All of the above

Answer 1

Answer:

d. All of the above

Explanation

wavelength(lambda)=1.0 angstrom=10^-10m

speed of light (c)=3×10^8m/s

3×10^8=nu(v)×10^-10

Ans(b.)... [nu=3×10^18s^-1]

For Option (a) & (c);;

(a) 3×10^18 Hz

So in this, Hz is also a unit of frequency(nu).

(c) 3×10^18 cycles per sec

So in this, cycles per sec is also a unit of frequency (nu).

# In Frequency(nu);;

Units are:: Hertz(Hz), s^-1, or cycle per sec [1Hz=1s^-1]

So option.(d)

All of the Above is correct answer for given ques.
