What is true about an object that looks red?
For an object to appear red, it must reflect only red light. All other colors are absorbed.
How do you differentiate light waves from sound waves?
You can see light waves (or particles . . .) but you cannot hear them. sound must travel thru matter , light can travel thru vacuum
If the frequency of the waves produced by a vibrating object increases how does the wavelength of the waves produce change?
As all EM waves do a constant speed ('c'). If the frequency increases (i.e. the waves are more frequent) the distance between the wave peaks (wavelength) must reduce. For visible light waves, this produces a 'blue shift.'
What substance to appear white what must happen to all wavelengths of light?
must be reflected
What is the frequency of a light wave with a wavelength of 650?
The velocity of the light waves must be given before the frequency can be find.
For a substance to appear black what must happen?
i think that it must reflect red light waves.

Why is it when you look in a pond from shore objects are not what they appear to be?
I believe the objects are what they appear to be, but not where they appear to be. This is due to the bending (refraction) of light waves as they travel through the water. The light coming to your eyes from the objects must pass through water, and then transition to air. The angle at which the light hits the boundary between the air and water determines how much the beam is bent. If you look straight down at an object in the water, it will appear to be in the correct place and orientation, but any other angle change the light, and therefore distorts the image.

The wavelength of light used to observe an object must be ... than the object itself?
The wavelength of light used to observe an object must be shorter than the size of the object itself.
What 3 things must happen to be able to see something?
1. there mush be a source of light 2.the light must strike an object 3.the light must be reflected from the object to your eye

How do you see the book on your tablecan you see the book in absolute darkness?
-- You "see" only when light enters your eye. -- You 'see' an object only when light from that object enters your eye. -- If the object itself doesn't generate light, then light from some other source must illuminate the object, and some of that light must reflect from the object to your eye. -- In absolute darkness, there is no light, and you do not 'see'.
What must happen for an astronaut to appear weightless?
He (or she) must float motionless and unattached to any object or cable.
