| 31. | Color-shifting inks reflect various wavelengths in white light differently, depending on the angle of incidence to the surface.
|
| 32. | The thickness of bolus applied is dependent on the skin dose required and the angle of incidence of the treatment beams.
|
| 33. | To optimise cruising efficiency, the angle of incidence can be adjusted by pumping fuel between the fore and aft tanks.
|
| 34. | In this sense the inclination of both faces of the lyre decreases the angle of incidence of sunlight on the clusters.
|
| 35. | Results vary with one or more than one of viscosity of the fluid, Mach number and angle of incidence changes.
|
| 36. | In all modern lenses the surface is coated to reduce abrasion, angle of incidence and the angle of refraction are equal.
|
| 37. | However, the feed does partially obscure the lens when the angle of incidence on the reflector is less than about 45?
|
| 38. | Hence, observed angles of incidence can be used to compute the direction and speed of a Cherenkov radiation-producing charge.
|
| 39. | For example, the amplitude of a reflection might increase with the angle of incidence, a possible indicator of natural gas.
|
| 40. | By varying the angle of incidence and take-off on the crystal, a single X-ray wavelength can be selected.
