I really enjoyed the experiments with light that we conducted last week! I was surprised to learn that light exists as a particle (called photons) and as a wave, and that we actually were preview to only small part of … Continue reading
CFL bulbs, or the energy saving bulbs touted by many, require mercury to produce light. All told, each bulb requires about 5 miligrams of Mercury- a dangerous heavy metal that must be respected and guarded against as it is toxic … Continue reading
Last spring, when I took astronomy 101 we talked a lot about spectra and light. While we discussed the definitions and applications of wavelength, frequency and speed of light waves, what I was most interested in was the different types … Continue reading
Given last week’s lecture about color and reflectivity, I wanted to share an artwork that I experienced while studying abroad in Denmark in the fall of 2013. Situated on top of a cube-shaped museum, called the ARoS in Aarhus, DK, … Continue reading
In class this week, we talked about how the human eye perceives color based on what wavelengths of white light are reflected from an object. However, what if the light that is hitting the object isn’t white to begin with? … Continue reading
Coming across one of the blog entries on rainbows, I immediately thought of the time when I saw the Northern Lights while on holiday. Till date, it is one of the most spectacular and breathtaking phenomenon I have ever seen! … Continue reading
Sound waves are a vibration (disturbance of air) that travels through a medium (air, water, a solid, etc.). The vibrations are different in size and shape, which is what produces different sounds. Sound waves can not exist in a vacuum … Continue reading
This week in class, we learned about the speed of light and how light can travel through objects like air and water, but can also travel through nothing in a vacuum. As I looked up more information about the speed … Continue reading
In watching Ron Hipschman’s talk about light and its properties such as speed, wavelength, and other relative measures, I was inspired to understand how this transmission of light and sound can be applied in everyday life. First and foremost, he … Continue reading
In doing some of this week’s readings, I came across some information on the formation of rainbows. Since I was little, I have long been obsessed with the idea of a rainbow and all of its psychedelic colors. I thought … Continue reading
