Effect of Group Work in Addressing the Misconceptions of Light
Type: Empirical, Anecdotal
Data collection method: Interview, Test
Number of subjects, range: Large — 31 or more
Grade and age of subjects: 9th-12 grade — 15-18 years
- Speed and angle of incident do not affect the bending of light.
- Ray of light is not always refracted in a definite direction.
- The refracted ray does not bend away from the normal as it travels from denser to a rarer medium.
- Lateral displacement does not depend on the thickness of the medium, angle of refraction, and angle of incidence.
- The color of the light, the material of the medium, and temperature do not affect the refractive index.
- If the angle of the incidence of the light while leaving the denser medium is zero, the light refracts.
- If the angle of incidence is greater than the critical angle, the total internal reflection of the light is not possible.
- Twinkling of star is due to total internal reflection of light.
- Total internal reflection won’t occur if the angle of refraction is 99° (greater than critical angle).
