light Flashcards
speed of light is less
high refractive index
refraction in low density to high
light bend towards normal line
high density to low
light move far
dispersion of which light is max
violet
speed of which colour is min in glass
violet
whviloet ray
lowest wave length and highest frequency
red light
high wavelength and low frequ
mirage formation
refraction and total internal reflection
dentist use which mirror
concave
concave mirrior
converge
canvex lens
converge
focal length of convex lens
positive and image is real and inverted
in which condition image form by cancave mirror is behind and virtual erect and magnified
between pole and focus
solar radiation visible
400-700 nm
wave length of visible light
390-780
eye is most sensetive to
yellow green light 5500 A
LIGHT TRAVEl in stratight line because
its wavelength is low
sun take aprox
8.5 min
when light travel from one medium to another the n what will not change
frequency
mirage
total internal reflection
car niror

concave mirroerag
image form by astronomical telescope
virtual and magnified
air buuble act like
concave lens
minimum heught to see a person
half
long sightness
convex lens
reading glass
convex lensmy
myopia
concave lens
eye visibility
25 cm
sunlight contains
7 colours
speed of which light is minimum and maximum
viloet minimum and red maximum
maximum deviation on prism
violet
for a critical angle light must pass from denser medium to rarer mediuum
image form in plane mirror
inverted and virtual
mirror use in torch
concave
focal length of concave lens
negative
in long sightness images are formed
behind retina
