Woolstenhulme 2 Paige Woolstenhulme Brother Neilson FDSCI 206: 01 16 March 2017 The Relationship Between Light & Sound (Combined Paper Version) Light and sound are two very different aspects of life, but at the same time, have more in common than one would assume. As is shown in the bubble chart on the front of this paper, light and sound connect in several different ways. But first, a explanation on both the physics and biology of each is necessary. Light: We began the class by learning about physics and how this has an effects on how light makes certain things possible. This is exemplified with our ability to look in a mirror and be able to see a reflection or how refraction makes objects look different while under water. It begins with the rays of light that emit from the sun. These rays either reach the ground uninterrupted, or are bent through different mediums, causing them to alter their direction. This light can cause reflections on a frictionless surface, or can bounce back from a more rough surface such as a curb or patch of grass. Light disperses, just as sound does, and can be reflected off of other rays of light, such as in a hall of mirrors. The biology of light, and how we see and interpret it, is much more complicated. The eye has many different layers that perform different functions. The retina lets in light, just as with a camera lense, and captures an image. This image sends photoreceptors up to the brain to the optic nerve Sound: The physics of sound begins with the waves that create sound. These waves can bounce off of objects, just as light does, and can also diffract and reflect. Sound is different in that it can add on itself by way of superposition, causing sound to add onto itself in layers. Different sounds are caused by different frequencies, and different notes are caused by the mixing together of different frequencies, just like a cookie vs. cake recipe call for different amounts of different ingredients. The biology of sound, just as with any human sense, is relatively more complicated than the physics aspect of it. We begin with our outer ear, which acts as a detector for sound. This leads to the ear canal which is chanel to the middle ear. The middle ear houses the Incus, which receives vibrations from the Malleus. Deeper into the ear is the Cochlea, which houses many small instruments. One of the most important of these is the Cochlea, which houses stereocilia, which are small hair like structures. These, when signaled, open gates that positive charges can come into the cell of the stereocilia, allowing neurotransmitters into the synapses made with the neurons of the spiral ganglion. This then creates action potentials, which are sent to the brain to be dealt with.

Woolstenhulme 3 Combine the previous paper parts into one paper that explains how a YouTube video or movie motivates us. Include the physics, biology, and psychology of light and sound. To add onto this paper, in order to turn it in for the last time as a complete combined paper, I will be using the video Sunday School by Lucien Hughes as an example. This video, a Simpson-Wave favorite, is one of the weirder and more popular Simpson-Wave videos on Youtube. This video, which is a music video slash parody slash art piece all in one, uses both hearing and sight in order to create an experience for the brain. Physically, this video includes a clip from a Simpson's episode where Bart is walking to church while listening eighties synth wave on a personal stereo, something his mother notices and quickly disapproves of in a church setting. The fact that is a vintage episode of the Simpson, being played with the effects of a VHS video tape, with what is essentially elevator music, brings up memories in our minds that are stored in a different part of the mind than those pieces would be if played separately. Through this we are working with our long term memory (top-down), and using it to create a new memory while also using our sensory memory (bottom-down) to file away what we are hearing the synth wave music and seeing with the collage of new images that move hand in hand with the music. Psy Biologically we are storing this visual information the same we we discussed in class: through a long route of light and motion detection, which then goes through the eyes, to the back of the eye, then to the interpretation part of the mind through a complex system of optical neural pathways, only to end up in our sensory memories, leading us to decide what to do with it, and then finally, ends up in our long term memories so that we can shuffle back to that info when needed. The hearing aspect of it is about the same, except for through the ear, to the inner ear, and through the neural pathways to be dealt with and stored. Psychologically, this youtube video is off the beaten path for most people, which is a reason that I chose it. Another is that is uses nostalgia to draw you in, and modern, yet vintage, beat to keep you coming back. It draws on both sides of your memory in order to make you feel comfortable, but not bored....
