Reflection Of Waves (physics Only) (GCSE Physics)

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?

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

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

When a pulse on a string reaches a fixed end and reflects, the reflected pulse:

Which scenario will produce a clear specular reflection of sound (an “acoustic mirror” echo)?

A concave mirror is used to reflect light. Which statement about rays parallel to the principal axis is correct?

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?

Which statement best describes why a rough (matt) surface does not produce a clear reflection?

Which property of a mirror causes a virtual image to be formed behind a plane mirror?

A laser beam strikes a mirror at an angle of 37° to the normal. A student measures the reflected beam and finds 41°. Which is the most likely cause?

A student shines a narrow beam at a flat mirror and measures the angle of reflection with a protractor. Which procedure will reduce systematic error?
