Answer:
Angle of reflection at plane surface of prism = 30°
Explanation:
Angle of reflection = angle of incidence at any surface plane or curved .
Here angle of incidence at plane surface of prism = 30°
Angle of reflection at plane surface of prism = 30°
If i be the angle of incidence and r be angle of refraction
sin i / sin r = refractive index
= 1.52
sin r = sin i / 1.52
= sin 30 / 1.52
= .5 / 1.52
= .3289
r = 19.2 °
Answer:
Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.
Explanation:
Sensation helps us to detect changes in our physical environment.
Sensation occurs in three steps,
- Sensory receptors, these detect stimuli.
- Sensory stimuli are converted into electrical impulses to be decoded by the brain.
- Finally, electrical impulses move along neural pathways to specific parts of the brain wherein the impulses are decoded into useful information.
Therefore, Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.
The guys before me was almost right. But instead of it being vertical it is horizontal.
