Fringe width (β) is given by β = λD/d, where d is the distance between the slits. If d is doubled, β becomes β/2, hence the fringe width halves.

The fringe separation is inversely proportional to the distance between the slits; thus, if the distance is doubled, the fringe separation halves.

The fringe separation is inversely proportional to the distance between the slits; halving the distance doubles the fringe separation.

Increasing the distance between the slits decreases the fringe width, which can lead to more visible fringes within a given distance on the screen.

Increasing the distance between the slits (d) causes the fringe width (β) to decrease, making the fringes narrower.

Increasing the distance to the screen increases the fringe width, as fringe width is proportional to the distance from the slits.

Increasing the distance to the screen increases the fringe width, as fringe width is proportional to the distance from the slits.

Fringe separation is directly proportional to the distance from the slits to the screen (D), so increasing D increases the fringe separation.

At the first minimum, the intensity is 0 due to destructive interference.

Fringe separation is directly proportional to the distance from the slits to the screen (D), hence it increases.

Moving the screen further away increases the distance (D) in the fringe width formula, causing the fringes to become wider.

Moving the screen further away increases the fringe spacing, as fringe width is directly proportional to the distance from the slits.

Fringe width β = λD/d = (600 x 10^-9 m)(1 m)/(0.5 x 10^-3 m) = 0.12 mm.

The distance between the fringes increases with an increase in wavelength, as fringe separation is directly proportional to wavelength.

Increasing the distance between the slits increases the fringe width because the angle of diffraction increases.

Moving one mirror changes the path length of one beam, causing the fringes to move apart or closer depending on the direction of movement.

Moving one of the mirrors changes the path length for one of the beams, causing a shift in the interference pattern.

Moving one of the mirrors changes the path length of one beam, causing a shift in the interference pattern.

Moving one of the mirrors changes the path length, causing a shift in the interference pattern (fringes).

The radius of the rings is directly proportional to the wavelength of light used. If the radius increases, the wavelength must also be increasing.

In a plane mirror, the image is formed at the same distance behind the mirror as the object is in front, so the image is at 10 cm.

When the angle of incidence equals the angle of emergence, the angle of deviation is equal to the angle of the prism.

The minimum angle of deviation (D) for a prism is given by D = A, where A is the angle of the prism. Therefore, for a 60-degree prism, the minimum angle of deviation is 30 degrees.

As the slit width decreases, the central maximum becomes wider due to increased diffraction.

The intensity of the central maximum is four times that of the first minimum in a single-slit diffraction pattern.

The intensity at the first minimum is zero, while the central maximum has maximum intensity.

In a single-slit diffraction pattern, there are theoretically infinite minima on either side of the central maximum.

The width of the central maximum is inversely proportional to the slit width. Halving the slit width doubles the width of the central maximum to 8 mm.

For single-slit diffraction, the first minimum occurs at sin θ = λ/a. Here, sin θ = 600 x 10^-9 m / 0.5 x 10^-3 m = 0.0012, θ ≈ 0.0698 rad ≈ 4°.

The angle for the first minimum in single-slit diffraction is given by sin(θ) = λ/a, where a is the slit width.
