X-ray, visible light and infared radiation are differnt from each other because:
--of differing frequencies-i know this is right
--of differing energies--i am not sure as to whether this is right or wrong because from what i understand, different frequencies could lead to different enrgies (blue has more energy than red, etc)
--of differing amplitudes--i know this is wrong
--of differing velociites--i know this is wrong
--they are not all electromagnetic waves---i know this is wrong
------------------
A stained glass window
--refracts light
--reflects light
--transmits light
--absorbs light
i am pretty sure about all of them being right except for transmitting light and refracting it. i think it could refract it because it turns it. i have no idea about transmitting light
-----------------------------------
light goes from air to water; angle of incidence = 30
i think light bends toward the normal because water has a greater index of refraction which slows light
--------------------------
light goes from glass to air; angle of incidence=30
pretty much the opposite of the previous one because it goes from a smaller index of recraction to a greater one
---------------------------------'
light slows down; angle of incidence=30
i don't think there is enough information to conclude whether this goes away or towards the normal
---------------------------------
used to magnify objects--i believe that this is a characteristic of concave mirrors and converging mirrors, but I'm not sure if it is characteristic of diverging mirrors--i believe that this NEVER makes an image larger
--------------------------------
an object inside a focal point of a convering lens forms an image that is
a.upright
b.upside down
c real
d virtual
e larger than the object
f smaller than the object
g the same size as the object
i'm sure it creates an upright and virtual image...but whether it is smaller or larger than the object I'm not sure, because it could be both depending on where it is looked from
-----------------------
the photoelectric effect
a can be used to create electric current
b occurs when light shining on a n emitting surface has a minimum intensity
c occurs when light shinng on an emitting surface has a minimum frequency
d supports the wave theory of light
e supports the particle nature of light
i'm pretty sure that a and b are correct, but i am not sure if e is correct
thank you in advance
