Disk 2 has the bigger moment of inertia, two different spinning disks have the same angular momentum, but disk 1 has more kinetic energy than disk 2.

Inertia causes a moving item to remain in motion at the same velocity (speed and direction) until acted on by a force. Everyday examples of the Law of Inertia (Inertia of Motion) People slump forward when the bus abruptly stops. When a bus driver abruptly applies the brakes, the lower part of the body comes to rest with the bus, but the upper section of the body continues to move forward due to inertia of motion. The Law of Inertia asserts that unless acted upon by an unbalanced external force, objects will remain at rest or move in a straight path in uniform motion.

A force is a push or pull that an object feels as a result of interacting with another thing. Each time two things come into contact, a force is applied to each one of them. After the encounter is finished, the force is no longer felt by the two objects. Forces are merely interactions; they do not exist in isolation.

When two objects interact and appear to be in physical contact with one another, contact forces are created. Several types of contact forces include frictional forces, tensional forces, normal forces, air resistance forces, and applied forces.

More 400-nm light would be reflected, because some of the light transmitted through the first layer could be reflected by the second layer, light transmitted by the second layer could be reflected by the third, etc. is the correct answer. The correct option is option (2).

In the case of multiple thin films stacked together in a butterfly's wing scale, interference effects play a crucial role in determining the light that is reflected. As light passes through each thin film layer, some of it is transmitted through the film, and some is reflected. The transmitted light then interacts with the subsequent layers and can be further reflected or transmitted.

The multiple layers of thin films create a complex interference pattern where the reflected light waves from each layer either reinforce or cancel out each other. This interference pattern depends on the thickness and refractive indices of the films.

For certain wavelengths of light, constructive interference occurs, causing those wavelengths to be enhanced and reflected more strongly.

Therefore, more 400-nm light (or other specific colors) would be reflected due to the constructive interference of light waves from the multiple layers of thin films in the butterfly's wings.

Diffraction is defined because of the interference or bending of waves across the corners of an impediment or thru an aperture into the vicinity of the geometrical shadow of the obstacle/aperture. The diffracting object or aperture successfully will become a secondary source of the propagating wave.

the diffraction phenomenon is defined by means of the Huygens–Fresnel principle that treats each factor in a propagating wavefront as a group of character spherical wavelets. The function bending sample is most reported while a wave from a coherent supply (inclusive of a laser) encounters a slit/aperture that is comparable in size to its wavelength, as shown in the inserted image.

This is because of the addition, or interference, of different factors at the wavefront (or, equivalently, each wavelet) that journey by way of paths of different lengths to the registering surface.
