What are the effects of refraction of light?
The effects of the wave nature of light include the reflection, refraction, dispersion, and diffraction of light, and its behavior during constructive and destructive interference. Everyday examples include: -- Mirrors, which would not work without reflection. -- Eyeglasses and the human eye, which would not work without refraction. -- Satellite dishes, which would not work without constructive interference.
What 2 conditions might change the rate of an enzymatic reaction?
pH and temperature
When does an object undergoes acceleration?
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.
What are the laws of refraction of light?
laws of refraction are as follows:=1) the incident ray, refracte dray and the normal at the point of incidence all lie on the same plane.==2) the sine of the angle of incidence to the sine of angle of refraction is a constant.this is also called the snell's law.=
The speed of light with a refraction index of 1.5 is?
2 x 108 ms-1

What is the difference from reflection and refraction?
REFLECTION: 1It is the phenomena in which a ray of light after striking a surface retuns back to the same medium. 2.reflection is carried out by the help of mirrors such as concave and convex mirrors. REFRACTION: 1.when a ray of light travels from one medium to another medium its speed changes and this change in speed causes refraction of light. 2.it is caused by lenses such as concace and convex lenses.
The resistance of an object to a change in the speed or the direction of its motion?

Why there is no refraction of light when light falls perpendicular to the boundary separating two media of different refractive index?
Take a look at the formula for refraction, and see what angle you get. n1 sin θ1= n2 sinθ2 Another way to look at it is simply "for symmetry reasons". If the incident ray of light were to be refracted in any other direction, why would one direction be preferred to another one? - In this case there is no "reference plane" to specify the direction.
Is y equals 2x-2 and y equals 2 parallel?
No. The slope of the first is 2 - ie a change in the horizontal direction results in double the change in the vertical direction. The second line is horizontal (slope = 0).
How do you go backwards in free rider 2?
You press Z to change direction.
What will be the change if a vector is multiplied by -2?
It will be twice as large as the original and have the opposite direction.
What 2 ways causes an object's velocity to change?
If an object's speed changes, or it heads off in a new direction, its velocity has changed. Because of friction and gravity 1. acceleration 2. deceleration 3. change of direction
When light passes into a glass block it changes direction what is the effect known as?
Light that approaches perpendicular to an interface between two different media (such as air and glass) *does not change direction*. Light that approaches such an interface at an angle other than 90° will change direction because the speed of light in the two different media is different. Simile: Think of a little red wagon running along a sidewalk, and one of its wheels drops off on the grass. The wheels on the sidewalk (like light through air) roll easily (like the speed of light in air), while the wheel in the grass (like light in glass) tends to want to roll more slowly for a given applied energy (like the lower speed of light in glass). The wagon will tend to suddenly turn fully out into the grass... (if it does not tip over and crash). it changes direction because the light is refracted.

Can light go through water?
The light will change directions (to be closer to the normal) once it hits the water. This is known as refraction which is a property of light. In this case, you have 2 media (plural form of medium). The two are air and water.The reason it changes direction is because air allows a different speed of light than water. Water is denser which is why light can't travel as fast. This change in the speed of light is what causes the light to change direction once it hits the water.In conclusion, after light hits the water, it will change directions (to be closer to the normal) due to the fact that the medium is changed (from air to water) which results in a change in the speed of light.
