Why is the ratio of angle of incidence to the angle of refraction is equal to constant?
Snell's law stipulates that the ratio of the sines as regards the angles of incidence in addition to that of refraction is a constant influenced by the media.
Which is larger the angle of incidence or the angle of refraction why?
The answer depends on the velocity of the Incidence IV and Refraction RV: sinI/IV = sinR/RV. The "why" is the conservation of time, LI/IV + LR/RV = constant.
What is the differenc e between drift diffusion current?
Specifically, drift relates the movement of a carrier (e.g., an electron or hole) to an applied electric field (i.e., the velocity of the carrier is proportional to the electric field, where the proportionality constant, mobility, is a quantity derived in solid-state physics). Diffusion relates the movement of carriers due to random (i.e., thermal) behavior and non-uniform distribution (i.e., the velocity of the carrier is proportional to the logarithmic derivative of the density of carriers, where the proportionality constant, the diffusion constant, is a quantity derived in solid-state physics).
Who's formulated the Snell's law?
it states that the ratio of sine of angle of incidence/sine of angle of refraction=constant, for the light of given color and given pair of medium. where n1 and n2 are the indices of refraction of light in different materials.
What feature allows rockweed to withstand the constant wave action of its environment?
holdfasts - apex
Does the index of refraction equal the angle of refraction?
Not exactly, the angle of refraction = the angle of incidence, which means the ratio of sine of angle of incidence to the sine of angle of refraction is constant for two media. That is sin i /sin r = constant , and this constant is called refractive index
Why is the ratio of angle of incidence to the angle of refraction is equal to constant?
Snell's law stipulates that the ratio of the sines as regards the angles of incidence in addition to that of refraction is a constant influenced by the media.
What is the grating constant for a 600 lines per mm diffraction grating?
1.667
What is necessary for simple diffusion?
1, concentration gradient 2. diffusion constant >0
Is the law of refraction the same for light rays going in either direction between the two media?
Yes. The laws of refraction are laws of physics and as such remain constant, as long as the space between the media is constant.
Are angle of incidence and angle of refraction proportional?
Yes. The proportionality constant is ' 1 '.
What will happen to the angle of refraction if the angle of incidence is made smaller for light passing from rarer to denser medium and how?
angle of refraction will also decrease as according to laws of refractio sin i/sin r= constant (CONSTANT IS THE REFRACTIVE INDEX OF THE MEDIUM).
Which best describes a material with a low index of refraction near 1?
The speed of light stays constant
Which is larger the angle of incidence or the angle of refraction why?
The answer depends on the velocity of the Incidence IV and Refraction RV: sinI/IV = sinR/RV. The "why" is the conservation of time, LI/IV + LR/RV = constant.
What is light from the viewpoint of physics?
Light is considered to have a dual nature. It can be considered as a transverse electromagnetic wave. This can explain phenomenon like Reflection, Refraction, Interference, Diffraction, Polarisation, etc. It can also be considered as particles called photons. Photons have energy E=hv. h is Plank's constant and v is the frequency of the radiation. This can explain phenomenon like the photoelectric effect.
Why do you not normall see refraction when you look across the room?
Because light is only refracted when it passes into a more or less dense medium. As the density of air is reasonably constant, refraction is not easily observable in your average room.
What is Snell's law?
it states that the ratio of sine of angle of incidence/sine of angle of refraction=constant, for the light of given color and given pair of medium. where n1 and n2 are the indices of refraction of light in different materials.
