When eye focuses on near objects is the degree of refraction of light entering the eye increase or decreased?
decreased
Why do distant objects ripple on a hot day?
Distance objects can be seen to "ripple" on a hot day because of refraction. As light from a distance object makes the trip to the observer, it passes through air of slightly varying densities. This causes it to "change course" to a degree, which is refraction. It is this thermally induced refraction that is responsible for the "ripple" we see, and for the mirage we sometimes hear about.
What is the speed of light through gelatin with a 2 degree angle of refraction?
186,282 m/second
What does refraction means in terms of rainbows?
Refraction of bending lightrefraction means the bending of light, and the refraction of light in a prism causes to 'split' light in all its colors (that we can see and not see)Refraction is the bending of light. The bending of light is defined mathematically by Snell's law. The degree of bending through rain drops produces the various colors of the rainbow.
Define critical angle?
critical angle is defined as angle of incidence provide an anlge of refraction of 90 degree
The refractive index of water is 1.33 a ray is incident from water on air at an angle of incidence equal to 30 degree what is the angle of refraction in air?
nwater * sin 30=nair *sin(angle of refraction) 1.33*0.5=1*sin(angle of refraction) sin(angle of refractiob)=0.665 angle of refraction inair=41.6 degrees nwater * sin 30=nair *sin(angle of refraction) 1.33*0.5=1*sin(angle of refraction) sin(angle of refractiob)=0.665 angle of refraction inair=41.6 degrees
Why does one feel thirstier after she or he drink soft-drinks?
Being thirsty is a brain response due to increased blood osmolarity or decreased blood volume. The human body must keep its blood osmolarity close to 300 mOsms in order to function properly. If it is increased or the blood volume is decreased the brain will release hormones such as ADH(antidiuretic hormone- to save water) and will trigger a thirst response in the brain. Soft-drinks as opposed to water, have an increased osmolarity and therefore cannot lower your blood osmolarity to the same degree as water and therefore do not relieve your thirst. Hope that helps
Is there anyone studying bachelor's degree online in Bangladesh?
Yes, this form of distant learning is coming to the twilight recently
What degree is a distant cousin?
Describing someone as a "distant cousin" is a very imprecise way of saying that they are related to you, but the speaker either does not know exactly how or they are not a first cousin, but are "more distant."
What degree of cousin is not reconized as related anymore 4th or 5th?
Every degree of cousin is related, whether second, fifth, or twentieth. The bigger the number the more distant the relationship.
What does the term ''refraction'' mean in terms of rainbows?
This refers to the degree at which the direction of the light rays change (ie 'bend') when they pass through drops of water.
Why is there an increased need for code of laws?
to ensure some degree of order and justice
