what do all waves in electromagnectic spectrum have in common?

• All Transverse waves

• Same wavelength

• Travel at the same speed

• Same frequency

Which of the following is a danger caused by Infra-Red

• Damage to skin cells

• Skin Burn

• Internal heating of body tissue

• Cancer

Formula of Stopping distance?

• Thinking Distance / Braking distance

• Thinking Distance x Braking distance

• Thinking Distance + Braking Distance

• Thinking distance - braking distance

What is the difference between Transverse and Longitudinal Wave

• Transverse oscillates perpendicularly towards the direction of energy transfer, Longitudinal oscillates parallel towards the direction of energy transfer.

• Transverse oscillates parallel towards the direction of energy transfer, Longitudinal oscillates perpendicularly towards the direction of energy transfer.

What happens during terminal velocity

• Air resistance equals weight force

• Air resistance is greater than weight force

• Weight force is greater than air resistance

• Magic

If you are skydiving on earth, does the weight force ever change? (e.g. increase or decrease)

• Yes

• No
