Answer:
Explanation:
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. ... When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction.Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another.
This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light. Without refraction, we wouldn’t be able to focus light onto our retina.Change in speed – if a substance causes the light to speed up or slow down more, it will refract (bend) more.
Angle of the incident ray – if the light is entering the substance at a greater angle, the amount of refraction will also be more noticeable. On the other hand, if the light is entering the new substance from straight on (at 90° to the surface), the light will still slow down, but it won’t change direction at all.
Answer: Context Effect
Explanation:
<u>Context effect</u> refers to <u>the influence that external factors (the environment, for example) have on the perception of a stimulus</u>. This is a well-known aspect of cognitive psychology.
In fact, the situation stated in this question is a good example: It is not the same to observe the Moon with a naked eye and taking into account factors such as cloudiness, dust and whatever is surrounding this view that have effects on the observation; than observing this same Moon with a narrow tube in which our eyes focus only on the lunar surface, without taking into account the rest that surrounds that horizon.
Answer:
C. Atoms Have same no. of Electrons and Protons
Explanation:
This is because we know that no. of Protons = no. of Electrons....
I hope it is simple to u.:-:-):-)
Heres one: If you were driving at night, and a car was coming toward you at high speeds, You could tell they were coming because of the increase of sounds and light. Hope this helps!
