Question

1. In your own words, what do you think the difference is between “sensation” vs. “perception.” Use the different aspects of a light wave (i.e. wavelength/frequency; amplitude; and purity) as examples in your explanation.

2. Amplitude of a wave is the height of a wave: Above, you've considered wavelengths of light/frequency of light and how that sensation gives you the perception of colors. Electromagnetic radiation can also vary in terms of amplitude which means that the EM waves can differ in terms of how tall or short the waves are. For example, take a look at the picture below. You see two waves which have the same wavelength (distance between crests)/same frequency (# of waves)--but they differ in terms of how tall or short the waves are. The tall waves are waves which have a high amplitude while the short waves are the ones with low amplitude. But how do we perceive this? That is, what is our experience of this? The top wave (high amplitude) would look brighter while the lower wave (low amplitude) would look dimmer. SO…the amplitude of an electromagnetic wave in the visible light range is perceived by us as _____.

High Amplitude Low Amplitude so...the amplitude of an electromagnetic wave in the visible light range is perceived by us as

Explanation / Answer

1. sensation is what you feel and perception is what you visualize.

consider white light.

you feel it to be white light with energy content . that is sensation.

by using a prism, you can see that it is actually consist of several different colours.

that is perception.

Q2. as wave with high amplitude looks brighter and wave with low ampltide looks dimmer,

and visible light range consists of bright colors, amplitude perceived by us is high amplitude.
