Jacob sets the wavelength on his spectrophotometer To 630nm and inserted a cuvette filled with liquid. The spectrophotometer determined the absorbable liquid to be 1.980, a very high value. Which of the following is most likely to be the transmit tan earlier value for the liquid?
65%
Andrew and Josh attended a carnival in their town. One of the attractions was a booth that sold silly glasses with lenses that had many curves. When Josh looked at Andrew through the glasses he looking different. Why did he look different?
Because the glasses cause the light to refract when light refracts it changes direction.
Stephanie bought a pair of sunglasses. The glasses are tinted and only allow blue wavelengths to pass through them. If Stephanie looks at a red car through her glasses, what color will she probably perceive it to be?
Black
Focus Question (pg 18) How does light wave interact with objects that reflect light?
Objects that neither absorb nor transmit light reflect light. When a light wave interacts with an object that reflects light, the angle at which the wave is reflected off the object is equal to the angle at which it encounters the object. (Law of Reflection)
Which if the following rays show how the flashlights beam will reflect off the mirror?
Ray B
Which of the following surfaces would reflect light?
A mirror
When light is reflected off a mirror, the angle of reflection is exactly double the size of the angle of Incidence.
FAlSE
Kirk has a plastic dish on his desk. The material that the dish is made of absorbs red and blue light and reflects green light. What color does Kirk probably perceive the dish to be?
GREEN
Emily is stirring a solution in a beaker with a glass stir rod. She notices that when she looks at the stir rod through the side of the side of the beaker, the rod appears "broken" however when she pulls the rod out of the rod is is a solid piece. Why did the rod look broken while it was in the beaker?
It goes from 1 medium to another so it to go through fraction and looks like the beaker is broken
What is happening when the lens in held in-front of the teddy bear?
Light is being refracted
Hannah buys a bottle because the water inside looks very blue; however, when she pours the water out of the bottle she discovers its clear. What was probably the reason that the water look different in the bottle?.
The bottle absorbs red/green/blue wavelengths
If a mirror which had a light reflecting off its surface was turned 15 degrees then the angle of reflection will change by 15 degrees.
TRUE
The extent to which light is refracted by a medium increases as the medium's index of fraction increases.
TRUE
Focus Question (pg 10) What is the relationship between the absorption snd transmission of light through transparent substances?
There is a direct relationship between the amount oflight transmitted versus that which is absorbed, as light interacts with a transparent medium.
The town of Kentwick has a lake that the citizens use to boat on. Unfortunately their boats propellers have been getting caught in weeds from the lakes underwater plants. Since the plants depend on sunlight to survive the mayor is considering adding a chemical to the water that greatly increases light absorption. How could this solve the towns problems.
With water absorbing the light means less light for the plants.
