Answer:

The two factors that affect the type of Shadows formed are stated below ::

  1. The distance between the source of land and the object.
  2. The angel where the ray of light falls on the object.
Dvinal [7]2 years ago

Answer:

The distance of the source of light from the object.

The angle at which the light rays fall on the object.

The size of the opaque object.

The size of the shadow depends on the distance of the source of light and on the angle at which the light rays fall on the object.

If the source of light is closer to the object, a larger shadow is formed than when the source of light is far from the object.

Explanation:

picture is in the top ️️️⬆️⬆️⬆️⬆️⬆️

It can be observed from the above figure that as the angle of light incident on the object changed the length of the shadow changed.

What is happens when a beam of light is traveling through air and is reflected by a glass surface?
DaniilM [7]

When a beam of light is traveling through air and is reflected by a glass surface, then the 2R / (1+R) is the total reflectance through a glass window.

To find the answer, we have to know about reflection.

<h3>What is reflection by glass surface?</h3>
  • Depending on the angle of incidence, the refractive indices of the glass and the light's source, some light is reflected when it strikes a glass surface (e.g., air).
  • The Fresnel equations can be used to calculate the percentage of transmitted and reflected light.
  • Both the front and the rear of glass reflect the light that is traveling through it. In fact, the light may mirror itself several times. Therefore, 2R / (1+R) is the total reflectance through a glass window.
  • These equations predict that ordinary soda-lime window glass will reflect around 8% of the light, assuming a perpendicular incidence angle and no absorption or scattering.

Thus, we can conclude that, when a beam of light is traveling through air and is reflected by a glass surface, then the 2R / (1+R) is the total reflectance through a glass window.

Net charge of system with one +6e sphere and another -4e sphere.
Ket [755]

Answer: +2 e

Explanation: Net charge of a system is sum of charges on all the constituents of the system.

The system contains two spheres. Charge on one sphere is:

q₁ = +6 e

Charge on the second sphere is:

q₂ = -4 e

Net charge of the system is:

q = q₁ + q₂

q = +6 e + (-4 e) = + 2 e

Thus, the net charge of system is +2 e.

A ray diagram is shown. what does the letter x represent?
kobusy [5.1K]

Answer: Letter X in the diagram represent the angle of incidence

Explanation: One of the properties of wave is reflection. But before reflection can occur, there must have been a directed motion of wave particle towards a plane surface. The angle of incidence is the angle between the direction of motion of the wave particle ( for example; light) and the normal to the plane surface.
