Answer 1

Answer:

sorry pati nhi hai aska answers

Answer 2

Answer:

7.12 μm

Explanation:

Given, frequency (f) = 4.21$\times 10^{13} Hz$

We know that  $wavelenth(\lambda) = \frac{speed (c)}{frequency(f)}$

⇒   $\lambda = \frac{3\times10^8m/s}{4.21\times10^{13}}$

⇒   $\lambda = 7.12 \times10^{-6}m = 7.12\mu m$

therefore, wavelength of an infrared wave is 7.12 μm.
