WebOct 26, 2024 · The X direction coefficient is greater than Y’s magnification coefficient. The Fourier curve with a frequency of 0.2~1 Hz increases with the slope of the raised terrain; when the El Centro is incorporated at 30°, the Fourier spectrum amplitude decreases as the incident angle increases in the low-frequency band. WebTotal Internal Reflection. When light is incident upon a medium of lesser index of refraction, the ray is bent away from the normal, so the exit angle is greater than the incident angle.Such reflection is commonly called "internal reflection".The exit angle will then approach 90° for some critical incident angle θ c, and for incident angles greater than the … grants king county https://manteniservipulimentos.com
