Ayoungs's double slit has separation of 2.5 x 10-5 m on wich a monochromatic light bean is directed. the resultant bright fringes on the screen 1.0 fro the double slit are separated by 2.3 x 10-2 m. what is the wavelenght of this bean?

575 nm

Explanation:

The variables in the given problem are Δy, λ, L, and d. In order to estimate the wavelength of the beam, we can use the equation below:

Δy = λ*L/d

Where:

Δy is the space between the fringes which is equivalent to 2.3*10^-2 m.

λ is the unknown wavelength in m

L is 1.0 m

d is the separation of the young's double slit which is equal to 2.5*10^-5 m

Thus:

λ = Δy*d/L = (2.3*10^-2)*(2.5*10^-5)/1 = 575*10^-9 m = 575 nm

Therefore, the wavelength of the beam is 575 nm.

explanation:

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
