Answer:

shallower.

Explanation:

To understand and to be able to solve this question, we have to understand the concept of Apparent depth and real depth.

If we have a bowl and water is filled to its brim, when you look inside the bowl full of water you will notice that the distance from the top of the bowl of water to the buttom seems a little bit closer this is known as as the APPARENT DEPTH and it is caused by REFRACTION.

The Snell's law can be used to show the relationship between the real depth and the apparent depth as given below;

n = real depth/apparent depth.

Refraction which is a property of wave causes the left sink which is filled with water to be able to bend. As light goes into water, it bends which will makes the left sink which is filled with water to appear SHALLOWER.

g Two radiation modes (one at the center frequency lIo and the other at lIO+?lI) are excited with 1000 photons each. Determine t

Schach [20]

Answer:

a) P=0.25x10^-7

b) R=B*N2*E

c) N=1.33x10^9 photons

Explanation:

a) the spontaneous emission rate is equal to:

1/tsp=1/3 ms

the stimulated emission rate is equal to:

pst=(N*C*o(v))/V

where

o(v)=((λ^2*A)/(8*π*u^2))g(v)

g(v)=2/(π*deltav)

o(v)=(λ^2)/(4*π*tp*deltav)

Replacing values:

o(v)=0.7^2/(4*π*3*50)=8.3x10^-19 cm^2

the probability is equal to:

P=(1000*3x10^10*8.3x10^-19)/(100)=0.25x10^-7

b) the rate of decay is equal to:

R=B*N2*E, where B is the Einstein´s coefficient and E is the energy system

c) the number of photons is equal to:

N=(1/tsp)*(V/C*o)

Replacing:

N=100/(3*3x10^10*8.3x10^-19)

N=1.33x10^9 photons

Can the velocity of a body revese the direction when acceleration is constant?

TEA [102]

Answer:

Yes, the velocity of the object can reverse direction when its acceleration is constant. For example consider that the velocity of any object at any time t is given as: ... At At t = 0 sec, the magnitude of velocity is 2m/s and is moving in the forward direction i.e.v (t) = -2.

Using dimensional analysis, show that energy can be calculated from the following energy equations. Hint, in SI, here we want Jo

anyanavicka [17]

Explanation:

1. The kinetic energy of any object is calculated as :

$E=\dfrac{1}{2}mv^2$ ...........(1)

Dimensional formula of energy, $[E]=[ML^2T^{-2}]$

Dimensional formula of mass is $[M]$

Dimensional formula of velocity, $[v]=[LT^{-1}]$

$[ML^2T^{-2}]=\dfrac{1}{2}[M]([LT^{-1}])^2$

So, $[ML^2T^{-2}]=[ML^2T^{-2}]$

LHS = RHS

2. The potential energy is given by :

$E=mgh$

Dimensional formula of mass is $[M]$

Dimensional formula of g is $[LT^{-2}]$

Dimensional formula of height is $[L]$

Dimensional formula of energy, $[E]=[ML^2T^{-2}]$

So, $E=[M][LT^{-2}][L]$

So, LHS = RHS

Hence, this is the required solution.
