Electromagnetic waves are waves consists of waves of the electromagnetic field, propagating through the space, carrying electromagnetic radiant energy. Examples includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum.

In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.

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.

If the polar ice capsmelted, how might this effect the length of the day?

Inessa [10]

Answer: It will increase the length of the day

Explanation: The polar ice caps contain the solid ice particles found around the polar regions,an increased temperature is a major cause of the melting of the polar ice Caps. When the polar ice caps melt especially in huge volumes they increase the amount of water flowing into the Sea this will cause a rise in the volume of the sea.

This rise in sea level will add some weights to Earth, making the Earth to rotate slightly lower than its normal speed,a slower rotation will lead to longer days.

Small blocks A and B are held at rest on a smooth plane inclined at 30° to the horizontal. Each is held in equilibrium by a forc

Olin [163]

<h3>Answer :</h3>

First of all, See the attachment for better understanding $.$

_________________________________

❂ Weight of block A :

➝ mg sin30° = 18

➝ W (1/2) = 18

➝ W = 18×2

➝ W = 36N 

❂ Weight of block B :

➝ N sin30° = 18

➝ (Mg cos30°) sin30° = 18

➝ W' (√3/2)(1/2) = 18

➝ W' (√3/4) = 18

➝ W' = 72/√3

➝ W' = 41.61N
