Answer: 655.7 nm

Explanation:

Given

The slits are separated by d=0.510\ mm

Distance between slits and screen is D=2.24\ m

Adjacent bright fringes are \beta =2.88\ mm apart

Also, the distance between bright fringes is given by  

\Rightarrow \beta =\dfrac{\lambda D}{d}\quad [\lambda=\text{Wavelength of light}]\\\\\text{Insert the values}\\\\\Rightarrow 2.88\times 10^{-3}=\dfrac{\lambda \cdot 2.24}{0.510\times 10^{-3}}\\\\\Rightarrow \lambda =\dfrac{2.88\times 10^{-3}\times 0.510\times 10^{-3}}{2.24}\\\\\Rightarrow \lambda =0.6557\times 10^{-6}\ m\\\Rightarrow \lambda =655.7\ nm

Which of the following materials offer the least electrical resistance? Pure water, wood, salt water, glass
Vanyuwa [196]

Salt water offers the least electrical resistance.

<u>Explanation:</u>

Least electrical resistance indicates that any material which readily allows the electric current through itself, and shows more conductivity.

Here pure water doesn't contain any ions, so it is a bad conductor.

Wood and glass are also bad conductors of electricity.

Salt water contains ions, which conducts electricity which means it shows least electrical resistance.
