Interference | Psychology | Chegg Tutors
Imagine a light wave that is like a very long sine wave. If you start at a crest and move an integral number of wavelengths, you will come to another crest. Such a wave is coherent. Laser beams have this property, and that is perhaps their most important characteristic. Sunlight, on the other hand, consists of lots of short segments of a sine wave, and the phase of one segment is not related to another. Two coherent light waves of the same wavelength may interfere. This means they can reinforce each other and produce a larger amplitude (constructive interference), or they may cancel each other out (destructive interference). In Fig. 32-1, the top two waves on the left are in phase. They add together to produce the lower curve there. The top two waves in the center are out of phase (more exactly, 180° out of phase). They cancel, as indicated by the straight line at the bottom. The waves on the right have some phase difference between 0° and 180°, and they result in a wave whose amplitude is reduced and whose phase is shifted.

TEACHING EXPERIENCE
I have tutored others ever since early middle school as a hobby. From assisting my classmates with homework to helping them understand lecture topics, I found tutoring to be not only a way to fulfill my need to reach out to others but also strengthen my own understanding of the topics I taught. In my last two years of high school, I formalized this hobby into a self-employed job during the summer by teaching underclassmen from my high school five days a week, seven hours a day. I taught numerous subjects ranging from SAT preparation to several AP subjects and my class size varied between one person to four or five. I utilized my summer tutoring job to make sure my knowledge didn't atrophy over the long summer breaks and to improve my communication skills involved in teaching others. Feedback from my students was generally positive and many returned in the following years. Overall, I love tutoring as a both a recreational and a financial interest.
EXTRACURRICULAR INTERESTS
I was born and raised in the Clear Lake area of Houston and my family hails from Taiwan. I graduated from Clear Lake High School as salutatorian in 2013 and currently attend the University of Texas at Austin as a pre-medical and Health Science Honors student. Outside of academics, I love gaming, specifically League of Legends and Hearthstone. Concerning tutoring, the main point I want students to know about me is that I focus on making sure they understand the concepts and theory behind a problem rather than just finding the answer.
