The problem was too big to type in my phone.
I hope my answer is readable.
P.S After the collision P is also moving in the same direction as Q.
Using the appropriate approximations:
dx/L = mλ
d = slit separation
x = fringe spacing
L = distance between slits and screen
m = some integer, used to determine the distance from the central bright fringe to another bright fringe
We don't really need a value for m because we're calculating the distance between any pair of consecutive fringes. Let's just set m = 1
Given values:
d = 1.0mm
L = 2.0m
λ = 480nm
Substitute the terms in the equation with our given values and solve for x:
1.0*10⁻³*x/2 = 480*10⁻9
<h3>x = 0.96mm</h3>
<u>Answer:</u>
<em>Due to the shortcomings in Piaget’s approach to cognitive development several other theories were put forward.</em>
<u>Explanation:</u>
Jean Piaget is the psychologist that offered explanations about cognitive development in children. There were several shortcomings in his theories and thus alternative theories about cognitive <em>development in children </em>were developed.
<em>Lev Vygotsky</em> proposed another explanation to children’s cognitive development. He strongly emphasized on the influence of culture on <em>children’s cognitive development</em>. He believes that it is through socio-cultural interactions development progresses.
He believed that individualized thoughts begin after these interactions. He take on <em>self-speech </em> was different from Piaget. Vygotsky considered self-speech as a guide to thinking while Piaget thought <em>self-speech to be egocentric. </em>
