Question

Calculate the Frequency of the radiation whose wavelength us 6000A​

Answer 1

Answer:

$5 \times {10}^{14}Hz$

Explanation:

Given

$\lambda = 6000Å \\ = > 6000 \times {10}^{ - 10} \\ = > 6 \times {10}^{ - 7}m$

$\boxed{Frequency = \frac{1}{T} = \frac{c}{ \lambda} }$

According to the 2nd formula of frequency

$Frequency = \frac{3 \times {10}^{8} }{6 \times {10}^{ - 7} } \\ = > \frac{ \cancel3}{ \cancel6} \times {10}^{8} \times {10}^{7} \\ = > 0.5 \times {10}^{15} \\ = > \boxed{5 \times {10}^{14} Hz}$

Here

c= Speed of light

λ= Wavelength

Therefore

Frequency of that radiation will be

5 X 10^14 Hz

Answer 2

Solution :

In this Question , We have Provided with the wavelength of 6000 Å and We need to Calculate the Frequency of the radiation .

Formula to Apply :

Frequency = Speed/Wavelength

⇒ ν = C/λ

Where ,

ν represents frequency of the radiation

C represents Speed of light

λ represents Wavelength

Finding the frequency of the radiation

Speed of light = 3* 10^8 m/s

⇒ ν = C/λ

⇒ (3 * 10^8)/(6000 * 10^10)

⇒ (3 * 10^8)/(6 * 10^-7)

⇒ (3/6) * 10^15

⇒ 0.5 * 10^15

⇒ 5 * 10^14 Hz

Therefore for the Wavelength of 6000 Å the frequency of the radiation is 5 * 10^14 Hz
