A person is randomly selected. What is the probability that the
person is:
a) Male?
b) Male and Color-blind?
c) Male given that the person is Color-blind?
d) Color-blind given that the person is Male?
e) Female given that the person is not

a) Copper solutions are typically blue to blue green in color.
What color of light would they be expected to absorb in the
greatest amount?
Red
Violet
Blue
Green
b) Based on your answer to the
previous question (hopefully you have the correct answer), what
wavelength range would you expect to see the maximum absorption of
light (in the visible range)?
500 nm to 600 nm
400 nm to 500 nm
300 nm to 400 nm
600 nm to 700...
Give a general description of the light and dark reactions of
photosynthesis. Light – light energy is converted into chemical
energy (ATP) Dark – Carbon fixation – carbon is fixed into organic
molecules (sugars) using ATP and enzymes
When violet light and yellow light shine on a metal surface,
only one color produces an electric current. Write 3 - 4 sentences
describing the effect of each light on the metal. Would increasing
the intensity of either type of light have an effect on the current
produced? How does quantization help to explain these observations?
(6 points) Please don't write too long :)
In visible light, which color has the longest
wavelength?'
Are Microwave, Visible Light, Gamma rays in order of lowest to
highest energy?
are Radio broadcast, cell phone and GPS examples of technologies
that uses radio waves
The illumination of an object by a light source is directly
proportional to the strength of the source and inversely
proportional to the square of the distance from the source. If two
light sources, one three times as strong as the other, are placed
11 ft apart, how far away from the stronger light source should an
object be placed on the line between the two sources so as to
receive the least illumination? (Round your answer to two decimal...
