Reflection Of Waves (physics Only) (GCSE Physics)

A light ray is incident on a mirror at 25° to the surface (i.e. 65° to the normal). What is the angle between the reflected ray and the normal?

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

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?

Which of the following best explains why polished metal makes better specular reflectors than white paint?

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

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 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?

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 student measures the angle of incidence and the angle of reflection on a flat mirror and finds small differences between the two angles each trial. What type of experimental error most likely explains the variation?
