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
What is total internal refraction?
When the angle of incidence is greater than the critical angle,the light ray reflects into denser medium at interface. This is total internal refraction
When light is traveling along the normal will its direction change?
This is total internal reflection where the angle of refraction is 90 degrees and its incident angle would be the critical angle(angle of incident for which the angle of refraction is 90).... This hapens when the angle of incidence is in a medium more dense than the angle of refraction's medium
What are characteristics of refraction?
1. When a ray of light travels obliquely from an optically rarer medium to an optically denser medium,it bends towards the normal at the point of incidence. in this case,angle of incidence is greater than the angle of refraction...
How do you compare the angle of incidence and the angle refraction?
The angles of light are the result of the law of sines: sine( incidence angle)/speed of incidence = sine(refraction angle)/ speed of refraction
What happens if the refraction angle is greater than ninety degrees?
This means no refraction occurs i.e. Total internal reflection (all light reflected) occurs
If the angle of incidence increases and the indexes of refraction stay the same what happens to the angle of refraction?
The angle if refraction also increases.
Why is the angle of incidence greater than the angle of refraction based on the magic pencil activity?
The angle of incidence is greater.
What is the incidence angle at which the angle of refraction is 90 degrees called?
A right angle.
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
How is refraction of light related to wave length of colors?
The longer the wavelength, the greater the angle of refraction.
What happens to light that moves from glass to air when its angle of incidence is greater than the critical angle?
It does not move from glass to air but undergoes internal refraction. That is, it is refracted back into the glass at the interface.
What is a angle called that is over 12 degrees?
An angle greater than 0 but less than 90 degrees is an acute angle An angle of 90 degrees is a right angle An angle greater than 90 but less than 180 degrees is an obtuse angle An angle greater than 180 degrees is a reflex angle
If a beam of light strikes a diamond at an angle of 45 degrees what is the angle of refraction?
17° to the normal.
What is total internal refraction?
When the angle of incidence is greater than the critical angle,the light ray reflects into denser medium at interface. This is total internal refraction
An angle whose measures is greater then 90?
When the angle = 90 degrees, it is a Right Angle. When the angle is greater than 90 degrees, it is an obtuse angle.
What angle mesures greater than 90 decrease?
An angle greater than 90 degrees is an obtuse angle or a reflex angle if it is greater than 180 degrees
