Light with a single wavelength falls on two slits separated by 0.510 mm. In the resulting interference pattern on a screen 2.24
scZoUnD [109]

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

What did Galileo discover when he dropped two cannon balls of different weights from the Leaning Tower of Pisa?
Nady [450]

Answer:

They fell at the same time.

Explanation:

Galileo was the first to discover the property of gravity, in which it makes everything fall at the same time in an airtight space. Gravity makes all objects fall and accelerate at 9.8m/s/s, regardless of weight, because the ratio between the weight of the object and the air resistance acting against it is a constant.
