Question

Which value is closest to the wavelength(in nm) of a quantum of light with a frequency of 6x10^15 Hz?​

Answer 1

Answer:

Solution:-

As we know that,

ν=

λ

c

⇒λ=

ν

c

where,

λ = wavelength of a quantum of light = ?

ν = frequency of a quantum of light = 8×10

15

s

−1

c = speed of light = 3×10

8

m/s

∴λ=

8×10

15

3×10

8

=0.375×10

−7

m=3.75×10

1

nm(∵1m=10

9

nm)

Hence, 4×10

1

will be the closest value to the wavelength (in nm) of a quantum of light with frequency 8×10

15

s

−1

.
