angle of incidence


Also found in: Dictionary, Thesaurus, Legal, Acronyms, Encyclopedia, Wikipedia.

an·gle of in·ci·dence

1. the angle that a ray entering a refracting medium makes with a line drawn perpendicular to the surface of this medium;
2. the angle that a ray striking a reflecting surface makes with a line perpendicular to this surface.
Synonym(s): incident angle

angle of incidence

the angle at which an ultrasound beam hits the interface between two different types of tissues, such as the facing surfaces of bone and muscle. The angle is also affected by the difference in acoustic impedance of the different tissues.

(anggĕl insi-dĕns)
1. Angle that a ray entering a refracting medium makes with a line drawn perpendicular to the surface of this medium;
2. Angle that a ray striking a reflecting surface makes with a line perpendicular to this surface.
Synonym(s): incident angle.

angle of incidence

the angle at which a body, object or vector is moving relative to another (e.g. a stationary surface or environmental factor such as wind), often prior to a collision. Example: when playing a snooker ball at a cushion, the angle between the ball's direction of travel and the cushion.

Combining these angles, we derive our final equation for the angle of incidence [[theta].
For carrier frequency and angle of incidence belonging to the frequency and angle intervals where GD and GS possess either negative values or values corresponding to the superluminal propagation, the form of informative packets (signals) is strongly distorted.
Also if the filter is supposed to have the same frequency response in response to the angle of incidence, this condition should be satisfied.
The thermopile sensor scans particular angle (Field of View (FOV)) and its output signal depends incident radiation and also on angle of incidence.
O'Brien found that later, as the sun rose and the angle of incidence of the sun's rays on the dusty vertical surface facing east decreased, the electrostatic forces on the vertical cell weakened.
The interception of the beam radiation by fabric surfaces is dependent on the angle of incidence, [theta].
When you're lighting mirrors, you have to remember that the angle of incidence equals the angle of reflection--which takes you back to your misspent youth in the pool hall, because banking a pool shot is the same thing.
The other potential advantage of the TXRF technique stems from the fact that the grazing angle of incidence is much smaller than the Bragg angle, named after the father and son pair who received the Nobel Prize in Physics for this work in 1915.
7-11) The second, more specialized technique is an external reflection approach undertaken at grazing angle of incidence, which is often referred to as RAIRS (Reflection-Absorption Infrared Spectroscopy), (12) or some other similar acronym.
The neutron angle of incidence to the magnet was optimized to achieve a separation of about 10 arcsec between the up- and down-spin neutron peaks [7] and a neutron count rate of about 10/s at each peak position (Fig.
If the angle of incidence equals the angle of reflection, is the view of Henriette's profile accurate?
