Ram covers distance of zoom in 50 seconds what is his speed

Light from a laser of wavelength λ1 shines normally on a pair of narrow slits separated by distance D. This results in a differe

Answer:

Explanation:

The angular position of first intensity maxima is given by the expression

= λ / d where λ is wave length of light and d is slit separation

putting the values given in the problem. ,

.02 = λ₁ / D

Now wavelength has been increased to 2λ₁

angular separation of first maxima

= 2λ₁ /D

= 2 x .02

= .04 radians.

Answer:

Identify the object to be analyzed. For some systems in equilibrium, it may be necessary to consider more than one object. Identify all forces acting on the object. Identify the questions you need to answer. Identify the information given in the problem. In realistic problems, some key information may be implicit in the situation rather than provided explicitly.
