Question

if light travels at the same speed in glass and wood glass lenses alter the direction of light rays​

Answer 1

Answer: NO

If light travels at the same speed in glass and air then glass lenses would not alter the direction of light rays.

Because refraction or bending of light occurs at the interface of two medians only due to the diffrence in speed of light in the two mediums.

Answer 2

Answer:

If light traveled at the same speed in glass and air, would glass lenses change the direction of light rays?

The answer is 'NO'

Explanation:

THE REFRACTION:  Refraction is the bending of a wave while it passes from one medium to another. The bending is brought on because of the variations in density among the 2 substances

The refractive Index is dimensionless. For a given material, the refractive index is the ratio between the velocity of light in a vacuum (c) and the velocity of light withinside the medium (v). If the refractive index for a medium is represented through n.

PROPERTIES OF REFRACTION:

• If the velocity of the wave will increase then the wave will propagate far from every day and the refractive perspective formed can be greater.
• In a denser medium, the molecules are compactly packed, as a result, it will become hard for a mild ray to penetrate through, hence lowering its velocity in denser mediums.
• The amplitude of the wave decreases on touring from rarer to denser medium.
• The wavelength of the wave varies however the frequency of the wave will continue to be unchanged on refraction.
• The amplitude of the wave rises on touring from a denser to a rarer medium.

The predominant purpose of refraction is the change in speed of light however no alternative in frequency while changing media. So no change in speed = no refraction.
