White coherent light $(400nm - 700nm)$ is sent through the slits of a Young's double slit experiment (figure.) The separation between the slits is $0.5mm$ and the screen is $50cm$ away from the slits. There is a hole in the screen at a point $1.0mm$ away (along the width of the fringes) from the central line.
→- Which wavelength (s) will be absent in the light coming from the hole?
- which wavelength (s) will have a strong intensity?
A small block of superdense material has a mass of $3 \times 10^{24}kg$. It is situated at a height h (much smaller than the earth's radius) from where it falls on the earth's surface. Find its speed when its height from the earth's surface has reduced to $\frac{\text{h}}{2}.$ The mass of the earth is $6 \times 10^{24}kg$.
→A ball moves along a curved path of radius 5m as shown in figure. It starts from point A and reaches point B. If there is no force of friction between the ball and surface of the path, then find the normal force that acts on the ball at the bottom (B) of the curved path.
To simulate car accidents, auto manufacturers study the collisions of moving cars with mounted springs of different spring constants. Consider a typical simulation with a car of mass $1000 \ kg$ moving with a speed $18.0 \ km / h$ on a smooth road and colliding with a horizontally mounted spring of spring constant $5.25 \times 10^3 N m ^{-1}$. What is the maximum compression of the spring?
Consider the above Example taking the coefficient of friction, $\mu,$ to be $0.5$ and calculate the maximum compression of the spring.
