Study Notes

Young's Double Slit Experiment

In a Young's double slit experiment, the slit separation is 0.3 mm, and the screen distance is 1m.
A parallel beam of light with a wavelength of 600 nm is incident on the slits at an angle α.
The point O on the screen is equidistant from the slits, and the distance PO is 11.0 mm.
The minimum value of α is required so that point P is a maxima.

Displacement of a Particle

The displacement of a particle is given by the equation x = A sin ωt + 2A sin(ωt + 2π/3) + 3A sin(ωt + 4π/3).
The amplitude of SHM is √(KA), where K is a constant.

Mono-atomic Gas and Cyclic Process

A mono-atomic gas undergoes a cyclic process.
The efficiency of the cycle needs to be found.

Longitudinal Sound Wave

A longitudinal sound wave is given by the equation P = 2.5 sin π(x – 660t), where P is in N/m², x is in meters, and t is in seconds.
The terminal speed of the sound wave needs to be found in cm/s, given ρL = ρ/2 = 1260 kg/m³ and g = 10 m/s².

Torque on a Square Loop

A square loop of side 10 cm is placed in the x-y plane with its center at the origin.
An infinite wire is located at z = 12 cm above the y-axis.
The torque on the loop due to the magnetic force needs to be found.

Uniform Circular Loop in a Magnetic Field

A uniform circular loop of radius 'a' has a specific resistance ρ and is placed in a uniform magnetic field B perpendicular to the plane of the figure.
A uniform rod of length 2a and resistance R moves with a velocity v.
