ASSIGNMENT 2.2 LIGHT AND SOUND WAVES ASS. 2.2 a. Nature of waves 1. What is a wave? Wave pulse and wave train? (5) 2. What are the differences between electromagnetic wave and mechanical wave? (5) ASS. 2.2 b.Characteristics of wave 1. Give the meaning of crest, trough, amplitude, wave length, “in phase”, “out of phase” , wave fronts and wave crests.(5) 2. Draw and label the parts of a wave. ASS.2.2c Frequency and speed of a wave 1.What is Frequency?Period?(5) 2. How is the speed of a wave determined? (5) ASS 2.2d Types of Wave 1. Differentiate longitudinal from transverse wave in a tabular form.(5) ASS 2.2 e Properties of Wave 1. What are the properties of a wave? Describe each. (5) 2.How are waves interfered? (5) 3. Is a standing wave a wave? Why (5) ASS 2.2 f Sound wave and Electromagnetic waves 1.What is a sound?(5) 2. How is it being produce?(5) 3. What is the speed of sound in air, water, wood, iron and aluminum?(5) 4. What are the properties of sound waves?(5) 5. How does temperature affect the speed of sound?(5) Ass 2.2 g Light Waves 1. Draw an illustration showing the arrangement of Electromagnetic waves in an spectrum.(5) 2. How are refraction and dispersion demonstrated in light?(5) 3. In the different colors of light, which is bent most and the least? Why?(5) 4. Why do we see spectacular events in the sky like rainbows, red sunset, and blue sky?(5) 1. a wave is a disturbance or oscillation that travels through space and matter, accompanied by a transfer of energy 2. a wave pulse is a short wave with no repeated oscillations. A pulse wave or pulse train is a kind of non-sinusoidal waveform that is similar to a square wave, but does not have the symmetrical shape associated with a perfect square wave. Wave train A succession of similar wave pulses. ta series of successive waves spaced at regular intervals ASS. 2.2 b. Characteristics of wave 3. ASSIGNMENT 2.2 LIGHT AND SOUND WAVES ASS. 2.2 a.
