Question

5 what is an effect of refraction? choose three.
the wavelength of light remains constant
light bounces off transparent objects
the apparent location of an object changes
the frequency of light changes
light’s path changes
light may be separated by wavelength

Explanation:

1. Analyze each option:

• "The wavelength of light remains constant": Incorrect. Wavelength changes during refraction as speed changes (since \(v = f\lambda\), frequency \(f\) is constant, so \(\lambda\) changes with \(v\)).
• "Light bounces off transparent objects": This is reflection, not refraction. Incorrect.
• "The apparent location of an object changes": Correct. Refraction causes apparent depth/position changes (e.g., a pencil in water looks bent).
• "The frequency of light changes": Incorrect. Frequency of light is constant during refraction (determined by the source).
• "Light’s path changes": Correct. Refraction is the bending of light when it enters a different medium, so its path changes.
• "Light may be separated by wavelength": Correct. For example, in a prism, refraction separates white light into its constituent wavelengths (dispersion).

Answer:

• The apparent location of an object changes
• Light’s path changes
• Light may be separated by wavelength
