In an interference pattern between two waves, a nodal point is a point where this will occur. constructive interference destructive interference a double trough a double crestWhich of the following cannot be used to explain the iridescence of a butterfly's wings? O diffraction and interference the tiny wedges found in its wings the thinness of its wings various pigmentations in wing colourWhich statement below about Young's Double-Slit Experiment is false? Diffraction of light occurs at both slits. OLight waves leaving the two slits have the same phase. The separation of the nodal lines is dependent on the wavelength of light. The interference pattern from this experiment has a nodal line down the centre of the pattern.Which of the following words or phrases indicate an occurrence of constructive interference: anti-nodal (or anti-node) bright dark destructive maximum (or maxima) minimum (or minimal nodal (or node)A straw placed in a drinking glass appears to bend as it hits the bottom of the glass. This phenomenon is caused by: refraction reflection diffraction Ointerference
