When a beam of white light is refracted, it spreads into
A 'green filter' would
We see yellow color on the screen because
For refraction of light, the angle of incidence must be
Tiny rain droplets act like a
The critical angle for water is
The refractive index of soda-lime glass is
The colors on the disk are mixed
In concave lenses, a distant object appears
A red "filter"
As the light moves from one medium to another, its
An example of 'refraction' of light is
To form other colors like brown, peach, purple etc. the colors that are required, are
If an object is extremely dense, light
An example of a device in which convex lens is used, is
The disk spun on rainbow to join its seven colors in order to make the effect of white light is known as
Light travels fastest through
Cones are also sensitive to
'Refractive index' of ice is
The light that has passed through a filter, is always
A red car looks red because it
'Refractive index' of silicon is
Who applied the word 'spectrum' to describe the rainbow of colors that combine to form white light?
If red, green and blue are mixed together, the formed color of light will be
Like sound, light travels as a
The scientist who presented the theory of dispersion of light was
The dispersion of white light into seven different colors is known as
The index that identifies each object is known as
The convex lens is also known as
Light is refracted in air. It enters our eyes through different angle this is why
