Question 1 (1 point) A straw placed in a drinking glass appears to bend as it hits the bottom of the glass. This phenomenon is caused by: O diffraction interference O refraction O reflection Question 2 (1 point) In an interference pattern between two waves, a nodal point is a point where this will occur. constructive interference a double trough a double crest O destructive interference Question 3 (1 point) Which of the following cannot be used to explain the iridescence of a butterfly's wings? diffraction and interference O the tiny wedges found in its wings O the thinness of its wings O various pigmentations in wing colourQuestion 4 (1 point) A wave transmits matter OO water energy particles Question 5 (1 point) Which statement below about Young's Double-Slit Experiment is false? O Diffraction of light occurs at both slits. Light waves leaving the two slits have the same phase. The separation of the nodal lines is dependent on the wavelength of light. O The interference pattern from this experiment has a nodal line down the centre of the pattern
