the time taken for a wavefront to pass a certain point

Which group contains only electromagnetic waves?

light waves, radio waves, γ-rays

light waves, radio waves, sound waves

light waves, sound waves, γ-rays

radio waves, sound waves, γ-rays

How do infra-red waves differ from ultraviolet waves?

Infra-red waves have lower frequencies.

Infra-red waves are longitudinal.

Infra-red waves have a lower speed in vacuo (in a vacuum).

Infra-red waves have smaller wavelengths.

The frequency of a wave is doubled. The speed of the wave does not change. What happens to the wavelength of the wave?

It becomes four times as large.

Which group contains only electromagnetic waves?

light waves, radio waves, γ-rays

light waves, radio waves, sound waves

light waves, sound waves, γ-rays

Pressure = height x density x gravity

Kinetic energy = 1/2 mass x velocity²

A student measures the length of a rod XY by holding it next to a metre rule. The student writes down the length as 94.8cm. Which statement is correct?

The value is incorrect because the student should subtract the reading for end Y from the reading for end X.

The value is incorrect because it should be 95.2cm.

The value is incorrect because it should be in millimetres.

What happens to the spring constant when the spring is stretched?

a) The spring constant remains the same

b) The spring constant increases

c) The spring constant decreases

d) The spring constant becomes zero

Which of the following is not an application of pressure in everyday life?

b) Using a pen to write on paper

a) Using a nail to hang a picture on a wall

c) Using a knife to cut vegetables

d) Using a syringe to inject medicine

An athlete runs at a speed of 8 m/s for 10 s, and then at a speed of 6 m/s for 12 s. Which calculation gives the average speed of the athlete in m/s?

( 8 ⋅ 10 ) + ( 6 ⋅ 12 ) 22 \frac{\left(8\cdot10\right)+\left(6\cdot12\right)}{22} 2 2 ( 8 ⋅ 1 0 ) + ( 6 ⋅ 1 2 )

8 + 6 2 \frac{8\ +\ 6}{2} 2 8 + 6

( 8 ÷ 10 ) + ( 6 ÷ 12 ) 22 \frac{\left(8\ \div\ 10\right)+\left(6\ \div\ 12\right)}{22} 2 2 ( 8 ÷ 1 0 ) + ( 6 ÷ 1 2 )

( 10 ÷ 8 ) + ( 12 ÷ 6 ) 22 \frac{\left(10\ \div\ 8\right)+\left(12\div6\right)}{22} 2 2 ( 1 0 ÷ 8 ) + ( 1 2 ÷ 6 )

What is the frequency of a wave?

the number of wavefronts produced per second

the distance that a wavefront travels every second

the distance from one wavefront to the next

the time taken for a wavefront to pass a certain point
