Answer:

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.

deff fn [24]

Answer:

2.8g/cm³

Explanation:

Given parameters:

Mass of cube = 42g

Volume of cube  = 15cm³

Unknown:

Density of the cube  = ?

Solution:

Density is defined as the mass per unit volume of a substance. It is mathematically expressed as:

 Density  = \frac{mass}{volume}  

So;

 Density  = \frac{42}{15}   = 2.8g/cm³
