Question

Which colour of light bends least anfwhich one the most while passing out from the prism .also state the reason for the same

Answer 1

red light bends the least because it has the longest wavelength and speed
violet bends the most because it has the shortest wavelength and speed
☆wavelength of red is 1.8 times that of violet
☆wavelength decreases from red to violet

Answer 2

The red color bends the least and the violet color bends the most because:

• Violet color has the minimum speed and has a shorter wavelength.
• Lights with shorter wavelengths are slowed more and hence they bend more than the other color lights.
• Red color light has the maximum speed and has a longer wavelength.
• Lights with longer wavelengths are not slowed much, hence they bend the least.
