incident ray การใช้

• It means that the light ray will emerge parallel to the incident ray.
• When the displacement is 45-degrees, the reflection is at right angles to the incident ray.
• For retroreflect light, producing reflected rays that travel back in the direction from which the incident rays came.
• It had been found that the incident ray, the reflected ray and the normal all lie in the same plane.
• A "'white body "'is one with a " rough surface [ that ] reflects all incident rays completely and uniformly in all directions ."
• The incident and reflected rays lie in a single plane, and the angle between the reflected ray and the surface normal is the same as that between the incident ray and the normal.
• A major challenge that must be addressed in any solar concentrating technology is the changing angle of the incident rays ( the rays of sunlight striking the mirrors ) as the sun progresses throughout the day.
• In specular reflection, the direction of the reflected ray is determined by the angle the incident ray makes with the surface normal, a line perpendicular to the surface at the point where the ray hits.
• The incident and reflected rays and the normal lie in a single plane, and the angle between the reflected ray and the surface normal is the same as that between the incident ray and the normal.
• With such surfaces, the direction of the reflected ray is determined by the angle the incident ray makes with the surface normal, a line perpendicular to the surface at the point where the ray hits.
• The exiting ray of the center wavelength is thus not only undeviated from the incident ray, but also experiences no translation ( i . e . transverse displacement or offset ) away from the incident ray's path.
• The exiting ray of the center wavelength is thus not only undeviated from the incident ray, but also experiences no translation ( i . e . transverse displacement or offset ) away from the incident ray's path.
• Many lenses that have been specially optimized for digital SLR cameras are nearly telecentric on the image side, to avoid the vignetting and color crosstalk that occur in color filter array-based digital image sensors with oblique incident rays.
• The inner hypotenuse shows the path of an incident ray and the outer hypotenuse shows an extension of the path of the refracted ray if the incident ray met a crystal whose face is vertical at the point where the two hypotenuses intersect.
• The inner hypotenuse shows the path of an incident ray and the outer hypotenuse shows an extension of the path of the refracted ray if the incident ray met a crystal whose face is vertical at the point where the two hypotenuses intersect.
• Diffraction gratings are constructed such that the angle of the incident ray, " ? i ", is related to the angle of the " m " th outgoing ray, " ? m ", by the expression
• The factor multiplying n _-is the sine of angle of the incident ray with the " x " axis, and the factor multiplying n _ + is the sine of angle of the refracted ray with the " x " axis.
• In vector form, if "'i "'is a unit vector pointing in the direction of the incident ray and "'n "'is the unit normal to the surface, the direction "'r "'of the refracted ray is given by:
• :You didn't say what article you're talking about, but in any case, the ray will only emerge parallel to the incident ray if the angles of bending are exactly opposite when it enters and leaves the glass, which will only happen if the glass surfaces are parallel on both sides.
• In anisotropic media such as some crystals, birefringence may split the refracted ray into two rays, the " ordinary " or " o "-ray which follows Snell's law, and the other " extraordinary " or " e "-ray which may not be co-planar with the incident ray.
