Core Practical 5.9 - Investigate Refraction in Glass Blocks

Question 1

Refraction:

Method:

Answer 1

• Draw around a glass block, which is on a piece of paper
• Shine a ray of light through, and trace where the light enters and leave
• Remove the block, and draw the line connecting them
• Measure incidence and refracted angle and record data on a graph (refraction on y)

Question 2

Refraction:

Equipment

Answer 2

• Glass Block
• Ruler
• Protractor
• Paper
• Ray box with single split

Question 3

Refraction:

Variables:

Answer 3

• Independent variable: Angle of incidence
• Dependent variable: Angle of refraction
• Control variables: Wavelength of the laser beam
