Which statement is true about standing waves on a string?

• The is always an antinode at each end

• The is always a node at each end

• There is a node at one end and an antinode at the other end

• There is always an antinode in the middle

The phenomenon associated with standing waves is called

• Reflection

• Refraction

• Resonance

• Absorption

When does total internal reflection occur?

• When the incident angle is greater than the critical angle

• When the incident angle is less than the critical angle

• When the refracted angle is greater than the critical angle

• When the refracted angle is less than the critical angle

When light travels from glass to air it refracts because

• the wave slows down due to an increase in density

• the wave speed up because of an increase in density

• the wave slows down because of a decrease in density

• the wave speeds up because of a decrease in density

Which statement about stationary waves in a pipe with both ends open is true?

• There are nodes at each end

• The are antinodes at each end

• There is a node at one end and an antinode at the other end

• There is always an antinode at the centre

The unit of frequency is

• Hertz

• Metres per second

• Metres

• Seconds

One microsecond is the same as

• 1 x 10^-6 seconds

• 1 x 10^-3 seconds

• 1 x 10^-9 seconds

• 1 x 10⁶ seconds
