Reflection Of Waves (physics Only) (GCSE Physics)

A plane mirror produces an image of an object. Which statement correctly describes the image formed by a plane mirror?

When a pulse on a string reaches a junction with a lighter string (lower linear density) and is partly transmitted and partly reflected, which is generally true about the transmitted pulse?

A water wave approaches a straight vertical wall at an angle. What is true of the angle between the incoming and reflected wave crests measured from the normal?

Which of the following correctly distinguishes specular and diffuse reflection?

A sound wave of frequency 500 Hz reflects from a large flat wall. If the incident wave has wavelength 0.68 m in air, what is true of the reflected wavelength?

Water waves of wavelength 0.5 m approach a straight wall at 30° to the normal and are reflected. What is the angle of the outgoing wave measured from the normal?

A light ray strikes a silvered glass made into a convex (diverging) mirror. Which is true of any image formed by a convex mirror for an object in front of it?

A transverse wave on a string meets a free end and is reflected. What happens to the phase of the reflected pulse?

A student uses a plane mirror to reflect a laser beam. If the mirror is rotated by 2° about its center, how much does the reflected beam direction change?

An echo is heard when sound reflects from a distant cliff. If the cliff is 170 m away and the speed of sound is 340 m/s, how long after the original sound is the echo heard?

A standing wave on a string is formed by reflection at both ends. Which condition is required at a fixed end?
