The eyepiece of a compound microscope is a convex lens.

The objective lens is the one closest to the object being viewed.

As the angle increases, the horizontal component of tension increases to provide the necessary centripetal force.

In a cyclic process, the system returns to its initial state, so the change in internal energy is zero.

In a cyclic process, the system returns to its initial state, so the change in internal energy is zero.

In a cyclic process, the net work done by the system is zero because the system returns to its initial state.

In a cyclic process, the system returns to its initial state, so the net change in internal energy is zero.

In a cyclic process, the system returns to its initial state, so the net change in internal energy is zero.

The damping ratio can be calculated using the logarithmic decrement method, leading to ζ = 0.25.

The time period of a damped harmonic oscillator remains the same; damping affects amplitude, not period.

In a damped harmonic oscillator, increasing the damping coefficient results in a decrease in the amplitude of oscillation over time.

Damping ratio (ζ) = c / (2√(mk)). If m is doubled, ζ is halved.

Increasing the damping coefficient results in a decrease in amplitude over time, leading to quicker energy loss.

In a damped harmonic oscillator, the amplitude of oscillation decreases over time due to energy loss.

The damping coefficient determines how quickly the energy is lost in a damped harmonic oscillator.

In a damped harmonic oscillator, the amplitude decreases over time due to the energy lost to damping forces.

In a damped harmonic oscillator, the amplitude decreases over time due to the loss of energy.

The damping coefficient determines the rate of energy loss in a damped harmonic oscillator.

The damping coefficient determines how quickly energy is lost in a damped harmonic oscillator.

Using E(t) = E_0 e^(-2ζω_nt), we find ζ = 0.2.

Increasing the number of slits increases the intensity of the maxima due to constructive interference.

Increasing the number of slits increases the sharpness of the maxima, thus decreasing the angular width.

Increasing the number of slits in a diffraction grating increases the sharpness of the maxima due to constructive interference.

The angle of diffraction is directly proportional to the order of the maximum in a diffraction grating.

In a diffraction pattern, the minima are always darker than the maxima, which have higher intensity.

Using the condition for the first minimum a sin(30°) = λ, we find the ratio a/λ = 1/√3.

The intensity of the central maximum is theoretically infinite compared to the first minimum, which has zero intensity.

The intensity of the central maximum in a diffraction pattern is at its maximum compared to other maxima.

The intensity of the central maximum in a diffraction pattern depends on both the wavelength of light and the slit width.

Fringe separation refers to the distance between two consecutive maxima in a diffraction pattern.
