Diffraction is the interference or bending of waves via an aperture into the area that is geometrically in the shadow of the obstruction or aperture. Effectively, the wave's secondary source is the diffracting element or aperture. The term "diffraction" was created by Italian scientist Francesco Maria Grimaldi, who also made the first precise observations of the phenomena in 1660. The wavefront's phase contributions are projected at an infinite number of spots (three are depicted) along length d, leading to a continually changing intensity on the registration plate. The Huygens-Fresnel principle, which views each point in a propagating wavefront as a collection of unique spherical wavelets, describes the diffraction phenomenon in classical physics. As seen in the enclosed figure, the distinctive bending pattern is most obvious when a wave from a coherent source (like a laser) comes into contact with a slit or aperture that is roughly the same size as its wavelength. This results from the addition or intensity maxima of various wavefront points (or, alternatively, each wavelet) that follow pathways to the registering surface of varying lengths.

To help you recall the direction of magnetic forces, use the right-hand rule. However, we can also modify the magnetic flux by introducing a wire loop into a magnetic field.

A magnetic field is created when current travels through a conductor. Individual magnetic fields are created as free electrons flow in one direction.

There are three things that can change the voltage's size: how big the magnetic field is. There are more flux lines, hence there are more flux lines for the conductor to cut.

At an angle of 33 degrees, the ray leaves the second mirror.

As per the below-attached figure:

The light beam is reflected at A, incident on the first plane at XA, and then incident on the second plane at XB, where it is again reflected as BY.

The law of reflection is the idea that when light rays strike a smooth surface, the angle of incidence and the angle of reflection are both identical. Additionally, the incident ray, the reflected ray, and the surface normal all reside in the same plane.

From the law of reflection of angle:

angle : BAO = θ = 34 degree

It is also given that,

Angle ABO = φ

Angle AOB = 113 degree

As in a triangle,

The sum of all three angles must be 180 degrees.

The work done by the force when the sled moves from x=0 to x=8 m is -2048 J

Force is a fundamental concept in physics that describes an interaction between two or more objects that results in a change in motion, shape, or energy of one or both of the objects.

Work done = W

Force = F

Distance = x

Area under the curve = A

Here, the distance moved is 8.0 m and the force is given by the graph as a function of x. Thus, we can use the area under the curve to calculate the work done from x = 0 to x = 8.

= W = F X x

= W = F ∫ x  (from x = 0 to x = 8.)

= W = - (4/3) X x³

= W = -2048 J

kinetic energy of an object is described as the energy that it possesses due to its motion which is also the work needed to accelerate a body of a given mass from rest to its stated velocity.

Answer:

Approximately 2.4 x 10^-8 N.

Explanation:

The force acting on the smaller object can be calculated using the formula for gravitational force:

F = G * (m1 * m2) / d^2

Where F is the force, G is the gravitational constant (6.674 x 10^-11 N * m^2 / kg^2), m1 is the mass of the smaller object (1.5 kg), m2 is the mass of the larger object (6.0 x 10^24 kg), and d is the distance between the two objects (6.4 x 10^6 m).

Substituting these values into the formula, we get:

F = 6.674 x 10^-11 * (1.5 * 6.0 x 10^24) / (6.4 x 10^6)^2

We can simplify this expression by dividing both sides by 6.0 x 10^24 to get:

F / 6.0 x 10^24 = 6.674 x 10^-11 * (1.5 / (6.4 x 10^6)^2)

Then we can simplify the right-hand side by performing the calculations in parentheses:

F / 6.0 x 10^24 = 6.674 x 10^-11 * (1.5 / (6.4 x 10^6)^2)

               = 6.674 x 10^-11 * (1.5 / 41.6 x 10^12)

               = 6.674 x 10^-11 * 3.6 x 10^-13

Finally, we can multiply both sides by 6.0 x 10^24 to get the value of the force acting on the smaller object:

F = 6.0 x 10^24 * (6.674 x 10^-11 * 3.6 x 10^-13)

 = 2.4 x 10^-8 N

Therefore, the size of the force acting on the smaller object is approximately 2.4 x 10^-8 N.
