Question

Если минимальная разность хода при котором две когерентные волны ослабляют друг друга при интерференции равна 280 нм то эти световые волны имеют длину

Answer 1

Дано   Δd=280 нм    л- ?

Δd=(2*k+1)*0,5*л
если k=0
л=Δd*2=560 нм - ответ

Answer 2

Calculating the Wavelength of Light Waves

To calculate the wavelength of the light waves, we can use the formula for the path difference in interference:

Path Difference (Δ) = *mλ*, where *m* is the order of the interference and λ is the wavelength of the light.

Given that the minimum path difference for which two coherent waves interfere destructively is 280 nm, we can use the formula to find the wavelength.

Calculation

Using the formula *Δ = mλ*, where *m* = 1 (for destructive interference):

280 nm = 1 * λ

Result

The wavelength of the light waves is 280 nm.
