It will not change. Glass slows light but does not change it frequency.
No, a light ray does not bend if it enters a glass block perpendicularly.
The speed of the light decreases, and its wavelength increases by the same factor.
Nothing. The speed changes. We live in a universe where electromagnetic waves change frequency if they can't change speed (and in a vacuum they can't), and only change speed if they enter another medium like glass.
The line is : the word ; Equal
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
when the light enters into another medium, its speed changes. Hence there will be the change in the wavelength. Speed = frequency times wavelength Since the speed of light is less is glass compare to the air, its wave length will be less in glass.
The speed of light and its wavelength decreases when it enters a new medium. The physicist Snell showed that it can vary.
it decreases
When light enters a glass block, it undergoes reflection and refraction. However at the glass air interface, refraction occurs to a larger extent than refraction and hence some of the light is reflected while the rest of it enters the glass block.
Red light (longer wavelength)
No, a light ray does not bend if it enters a glass block perpendicularly.
what happens when light enters a polorizing filter?
If the light enters the prism at an angle the light will bend. The amount the light will bend depends on its wavelength. Each wavelength is bent a different amount effectively splitting the light into its constituent wavelengths. Visible light (390 - 750 nm) will split into a rainbow. see link below
The atoms in glass molecules are further apart than the wavelength of light, which allows the light to pass through.
Pupils "constrict" when light enters, and "dilate "when the lighting dims
The speed of the light decreases, and its wavelength increases by the same factor.
the light must be coherent - which happens when a single beam of light is split
