Reflection Of Waves (physics Only) (GCSE Physics)

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

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 ray of light strikes a plane mirror with angle of incidence i (measured from normal). Which expression gives the angle between the incident ray and the reflected ray?

A plane wavefront approaches a flat mirror. The angle between the incident wavefront and the mirror is 40°. What is the angle between the reflected wavefront and the mirror?

Which of the following correctly distinguishes specular and diffuse reflection?

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 fixed end and is reflected. What happens to the phase of the reflected wave?

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?

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

A sound wave in air strikes a smooth wall and is reflected back. Which statement is true about the reflected sound?

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